Unit 3 test: Thermochemistry Honors Form B

Front

What state of matter is present during condensation?

Back

Gas to Liquid

Front

What type of change occurs when dry ice sublimates?

Back

Endothermic change

Front

What is the specific heat of water in cal/g°C?

Back

1.00 cal/g°C

Front

How do you calculate the final temperature of water when heat is removed?

Back

Use the formula: Q = mcΔT, where Q is heat lost, m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What is the kinetic energy formula?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect kinetic energy at the same speed?

Back

Kinetic energy increases with mass if speed is constant.

Front

What is the direction of heat flow between two objects?

Back

Heat flows from the object with higher temperature to the object with lower temperature.

Front

What is an example of an exothermic process?

Back

Combustion of fuels, such as burning wood.

Front

What is an example of an endothermic process?

Back

Melting of ice or sublimation of dry ice.

Front

What happens to the temperature of water when it absorbs heat?

Back

The temperature of water increases.
