Thermochem chp 17-1 Quiz

Temperature is a measure of the...

• total energy in a substance
• total kinetic energy in a substance
• average potential energy in a substance
• average kinetic energy of molecules in a substance

The transfer of thermal energy between objects of different temperatures is called...

• temperature

• heat

• internal energy

• enthalpy

A substance with a high specific heat...

• is always extremely hot.

• requires a lot of energy to become hot.

• experiences rapid temperature changes.

• From a lower temperature object to a higher temperature object.
• From an object with lower kinetic energy to an object with higher kinetic energy.
• From an object of higher mass to an object of lower mass.

Over time, the temperature of a glass of cold water will...

• match the temperature of the surrounding environment.

• become colder still, as heat is transferred to the surrounding environment.

• become warmer than the surrounding environment.

• not change temperature.
