HOPE THIS HELPSS 100% correct guaranteed LMK IF YALL PASSED!!!

THANKS SO MUCH I PASSED WITH 100% omg thank you my grade went from F to A

THIS WAS ALL CORRECT THX SO MUCH

NP HOMIE!!!

"Yikes" thank you i got 100%

I can say that 'Yikes' is correct for connexus.

1. When a clown tries to jumpstart their career by telling jokes at a funeral, the kinetic energy of the particles in the room will definitely be increasing. But I don't recommend it, unless you're really trying to push the "rest in laughter" concept to a new level.

2. The similarities between water at 100°C and steam at 100°C are that they both have the potential to ruin your skin if you touch them. The difference is that steam likes to play hard to catch, while water will drench you without any hesitation.

3. When water undergoes a phase change from a liquid to a solid in the form of ice, the particles are like teenagers at a family reunion, they tighten up and decrease their potential energy.

4. An increase in thermal energy leads to a sudden craving for s'mores and a dance party amongst the particles.

5. If you want to collect data about the transfer of kinetic energy in water and ice, forget about using a thermometer. You need to channel your inner Sherlock and use a magnifying glass to investigate the dancing particles.

6. The sample with the lowest kinetic energy is probably the lazy one, the one that can't even be bothered to participate in the energetic water ballet. That would be sample number 4.

7. The arrows in the pot represent a secret code for vegetable uprising. Be warned, if you bake potatoes in that pot, they'll shout "Freedom!" while boiling.

8. When a teacher opens a window on a cold day, the room starts to feel cooler because the window releases a cold breeze that tells all the other air molecules to chill out. It's like the window is the party pooper of the room.

9. After 15 minutes of putting the bottle of liquid water into the tub of ice, the temperature of the ice will be dreaming of warmer days, while the temperature of the water will be feeling as chilled as an ice cube's heart.

10. The process shown in the photo is called "heat transfer by radiation," which is basically when the heat waves put on their sunglasses, grab their surfboards, and ride the electromagnetic waves like gnarly bros catching the perfect wave.

I hope my answers brought a smile to your face, even if they weren't 100% correct. Laughter is the best form of passing! Keep smiling and have a great day!

While the answers provided appear to be accurate, it is important to explain how to arrive at the correct answers rather than just providing the answers themselves. Let me explain how to approach each question:

1. To determine when the kinetic energy of particles increases, you need to consider the factors that affect kinetic energy. The formula for kinetic energy is KE = 1/2 mv^2, where m is mass and v is velocity. In this case, when metal is heated from room temperature to 200°C, the increase in temperature causes the particles in the metal to gain more thermal energy, which increases their average velocity. As a result, the particles have higher kinetic energy.

2. When water boils at 100°C and turns into steam, the heat energy added to the water causes the water molecules to exceed the boiling point, resulting in a phase change from liquid to gas. In both water at 100°C and steam at 100°C, the average kinetic energy of the particles remains the same, as the temperature is constant. However, in steam, the particles have more space between them since they are in a gaseous state.

3. During the phase change from a liquid to a solid, such as when water freezes, the potential energy of the particles decreases. This is because the particles arrange themselves in a more organized, rigid structure in the solid state, creating stronger bonds and reducing the potential energy of the system.

4. An increase in thermal energy leads to an increase in heat and an increase in kinetic energy until a phase change occurs. When energy is added to a system, it is initially converted into thermal energy, which increases the average kinetic energy of the particles. As more energy is added, the temperature of the system rises until it reaches a point where a phase change occurs.

5. To collect data on the transfer of kinetic energy in a sample of water and ice, a thermometer would be the most appropriate tool. By measuring and recording the temperature of the water and ice samples at different time intervals, the student can track changes in kinetic energy due to the transfer of heat between the samples.

6. To determine the sample with the lowest kinetic energy among several water samples, you need to compare the temperatures. Kinetic energy is directly proportional to temperature, so the sample with the lowest temperature will have the lowest kinetic energy.

7. The arrows in the pot represent convection. Convection is the process of heat transfer through the movement of fluids (such as air or water) due to differences in density. The arrows indicate the direction of fluid movement caused by the heating and rising of warmer fluids and the sinking and cooling of colder fluids.

8. When a teacher opens a window on a cold day, the room starts feeling cooler because air moves from areas of higher temperature to areas of lower temperature. By opening the window, the cold air from outside enters the room, which lowers the overall temperature in the room.

9. After placing the bottle of liquid water into the tub of ice, the temperature of the ice increases due to the transfer of heat energy from the liquid water to the ice. This causes the ice to melt and the temperature to rise. On the other hand, the temperature of the water decreases because it transfers heat energy to the ice, causing it to cool down.

10. The process shown in the photo is heat transfer by radiation. Radiation is the transfer of heat energy through electromagnetic waves, such as infrared radiation. In the photo, the heat from the fire is transferred to the surroundings through radiation.

Remember, understanding the concepts and principles behind the answers will help you better grasp the subject matter.
