Thermal Energy Calculation

If you brought sample A and B close together , in what direction would heat be transferred?

• From sample A to sample B

• From sample B to sample A

• Heat would not be transferred.

• sample A and sample B would both transfer heat to each other.

even though sample A has a higher temperature, sample B has a higher thermal energy. Pick the correct explanation from the choices below

• the molecules in sample B are brown and have high energy

• the molecules in sample A are yellow and have low energy

• thermal energy is higher when temperature is lower

• there are many more molecules in sample B which make the total energy higher

The total energy of all the particles in a sample of matter is called —————

• Total Energy

• Thermal Energy

• Kinetic Energy

• Particle Energy

Thermal Energy depends upon the energy of the particles as well as the number of particles. Which would have more thermal energy, a small cube of Ice at zero Celsius or a large cube of ice at zero Celsius?

• The large ice cube because it has more particles than the small ice cube

• The small cube of ice because it will melt faster than the large ice cube

• Neither, they are cold so they do not have thermal energy

• both have the same thermal energy because they are both at zero Celsius.

Specific Heat

• Materials that do not conduct heat well.

• A material that conducts heat well,

• The amount of energy required to raise the temperature of 1 kilogram of a material by 1 kelvin.

• The expansion of matter when it is heated.
