Heat Check-In

What unit do you use to measure Thermal Energy?

• J/Kg ºC
• Kg
• ºC
• J

What letter is used to represent specific heat capacity?

• H

• P

• C

• T

A high specific heat means...

• It heats up quickly with energy added
• It requires more energy to change temperature

What  is the formula to calculate heat energy required to raise the temperature of any substance?

• Q=mc∆t
• Q=mc
• Q= ½mv
• m=QC

Specific heat of water is  4.18 J/g°C. Specific heat of wood is 1.760 J/g°C What material needs more heat energy to raise the temperature?

• Water
• Wood
• Both are same

Copper, Stainless Steel, Carbon Steel, and Zinc were all heated using the same thermal energy.  What material would be the coolest after being heated?

• Copper
• Carbon Steel
• Zinc
• Stainless Steel

The molecules of a liquid vs. a solid....

• Move slower in a liquid.
• Move slower in a solid.

If you place some Gatorade in a cooler with ice...

• It's particles will speed up.
• It's particles will slow down.

A measure of the average kinetic energy of the individual particles in an object is called:

• thermal energy
• conduction
• convection
• temperature

Observe the diagram. Which statement is true about the kinetic energy of the molecules in the containers?

• The molecules are moving faster in Diagram A

• The molecules are moving slower in Diagram A

• The molecules are moving at the same rate in both diagrams
