number #2

The lake will have more total thermal energy, but the particles in the coffee will be moving faster.

sorry this is actually the right answer for #2 my bad i put the wrong one

hail hyrdra is right !!!! tysm

1. What is kinetic energy?
a) thermal energy
b) the energy of motion
c) the energy of radiation
d) stored energy

2. A fisherman in a boat is drinking hot coffee. The large lake below his boat is full of cold water. Which statement is an accurate comparison of the lake water and the coffee?
a) The lake will have more total thermal energy, but the particles in the coffee will be moving faster.
b) The coffee will have more total thermal energy, and the particles in the coffee will be moving faster.
c) The coffee will have more total thermal energy, but the particles in the lake water will be moving faster.
d) The lake will have more total thermal energy, and the particles in the lake water will be moving faster.

3. The gallium in the image is melting in the person’s hand. Which changes will occur on a microscopic level?
a) The gallium atoms will gain kinetic energy.
b) The gallium atoms will gain potential energy, moving freely from each other.
c) The gallium atoms will increase in temperature.
d) The gallium atoms will be moving faster on average.

4. Which object will have particles with the highest average kinetic energy?
a) water at 37°C in a glass
b) water at 40°C in a swimming pool
c) a drop of water at 90°C
d) an iceberg at 0°C

5. Thermal energy is transferred to a substance. Which change can occur?
a) The kinetic and potential energy of the particles will stay the same.
b) The particles will gain potential energy, but the kinetic energy of the particles will stay the same.
c) The particles can gain potential and kinetic energy.
d) The particles can gain kinetic energy, but the potential energy of the particles will stay the same.

The correct answers are:
b
a
b
c
c

i got 100 on my test tysm hail hydra you just made my day

hail hydra is right thx :0

Thanks Hydra

D
C
A
D
B
Thanks hydra!

Just wanted to give out answers
For the kinetic and thermal energy quick check I got #2 wrong these are correct have a great life

1.What is kinetic energy?
the energy of motion

2. A fisherman in a boat is drinking a cup of hot coffee. The large lake below his boat is full of cold water. Which statement is an accurate comparison of the lake water and the coffee?

The LAKE will have more total thermal energy, and the particles in the coffee will be moving faster.

3. The gallium in the image is melting in the person’s hand. Which changes will occur on a microscopic level?

The gallium atoms will gain potential energy, moving freely from each other.

4. Which object will have particles with the highest average kinetic energy?

a drop of water at 90°C

5. Thermal energy is transferred to a substance. Which change can occur?

The particles can gain potential and kinetic energy.

i messed up on number 2 because you put the wrong answer put i have used jiskha on all my quick checks today and got a lot of 100% so 1 question wrong wont be bad thanks for the answers

you lyer

i got em all wrong

cool

beeevee is correct except number 2 is wrong the answer was actually BUT not AND

#2 is the lake will have more total thermal energy but the coffee particles would be moving faster

hydra is wrong i got all of them wrong the answers are
D. the energy of motion
D. The lake will have more total thermal energy, but the particles in the coffee will be moving faster.
B. The gallium atoms will gain potential energy, moving freely from each other.
C. a drop of water at 90°C
C. The particles can gain potential and kinetic energy.

@sunflower is 100%

@Hail Hydra, @sunflower, @Not Kool-aid Gurl, @BeeVee, and @htsrhtdyjy are all confirmed to be correct. TYSM guys, Y'all really helped everyone and I appreciate y'all. 🙏

BTW, I called Captain America and he's coming back for the Hydra cult LOL
