What is the formula for Heat Capacity?

• U = Q - W

• H = Cp x T x J

How many joules of heat are required to raise the temperature of 20.0 grams of water from 30.0°C to 50.0°C?

Specific heat of water = 4.18 Joules/g ° C

• 1,672 Joules

• 836 Jouels

• 418 Joules

• 418 grams

Temperature is defined in physics as....

• The amount of heat

• Farenheit

• the measurement of the average kinetic energy of molecules of a substance

• Kelvin

During which interval is the average kinetic energy of the molecules of the substance unchanged?

• AB

• BC

• CD

• AD

Which direction will heat flow?

• Block 1 will transfer heat to Block 2 by convection

• Block 1 will transfer heat to Block 2 by conduction

• Block 2 will transfer heat to Block 1 by conduction

• Block 2 will transfer heat to Block 1 by radiation

where is convection happening

• A

• B

• C

• D

What type of heat transfer is the sun transfering heat to the Earth

• Conduction

• Convection

• Radiation

• Induction

Warm air above large bodies of water rises into the atmosphere, carrying with it water vapor that forms clouds. Likewise, as air in the upper atmosphere cools, it falls back to the lower atmosphere, where it is warmed once again. This cycle of atmospheric heat transfer is an example of —

• Conduction

• Convection

• Radiation

• Specific Heat

When a gas or vapor goes into a liquid phase, has heat been added or removed (assume pressure does not change)

• Heat is added

• Heat is removed

• Heat remains constant

What is the a unit of measurement for Heat energy

• Joule

• calorie

• Celcius

• Farenheit
