Energy Transfer and Temperature Quick Check:
What is the best description of thermal energy?
A: Thermal energy is a type of kinetic energy.
Which scenario correctly illustrates heat?
B: cold person’s hands get warmer by holding a rock that has been sitting in the sun
What happens when two substances with different temperatures come into contact?
A: Thermal energy is transferred from the warmer substance to the cooler substance
Why do restaurants wash their dishes with hot water?
C: The molecules of hot water have more kinetic energy than the molecules of cold water, so they will more easily break up grease and leftover food.
Which is the best example of a thermal conductor?
D: copper plating on bottom of a skillet
The best example of a thermal conductor from the options given would be copper plating on the bottom of a skillet. Copper is an excellent conductor of heat, which means that it can quickly transfer heat energy from the stove to the food being cooked.
Well, if I were to be a bit cheeky, I would say the best example of a thermal conductor is obviously a flaming hot potato! But if we're sticking to the given options, I would go with the copper plating on the bottom of a skillet. Copper is known for its excellent heat conductivity, so your pancake flipping skills can benefit from it!
The best example of a thermal conductor from the given options is the "copper plating on the bottom of a skillet." Copper is an excellent conductor of heat, which means it can efficiently transfer and distribute heat across its surface.
To determine which is the best example of a thermal conductor among the given options, we need to understand what a thermal conductor is. A thermal conductor is a material that allows heat to pass through it easily.
Now, let's analyze each option:
1. Plastic ice-cube tray: Plastic is generally considered a poor conductor of heat. It does not allow heat to flow through it efficiently, so this option is not the best example of a thermal conductor.
2. Copper plating on the bottom of a skillet: Copper is an excellent conductor of heat. It has high thermal conductivity, which means it can efficiently transfer heat. This option is a good example of a thermal conductor.
3. Down jacket: Down jackets are commonly used to insulate and keep the wearer warm. Down, which is the soft feathers from birds, acts as an insulator by trapping air to create a barrier against cold. It inhibits the flow of heat, so it is not an ideal thermal conductor.
4. Ceramic stovetop: Ceramic, like plastic, is also a poor conductor of heat. Ceramic stovetops are designed to withstand high temperatures and can transfer heat to cookware efficiently, but they themselves do not conduct heat well. Thus, this option is not the best example of a thermal conductor.
Based on the explanation above, the best example of a thermal conductor among the given options is the copper plating on the bottom of a skillet.
