Chapter 1: Heat, Temperature, and Pressure

Temperature is defined as

• heat content

• the level of heat intensity

• the British thermal unit

• the absence of cold

The standard conditions for water to boil at 212°F are

• an atmospheric pressure of 14.696 psig, or 29.92 in Hg.

• an atmospheric pressure of 0 psia, or 29.99 in Hg.

• an atmospheric pressure of 0 psig, or 0.92 in Hg.

• an atmospheric pressure of 14.696 psia, or 29.92 in Hg.

Fahrenheit, Celsius, Rankine, and Kelvin are

• temperature scales

• pressure scales

• Btu measurements

• heat transfer methods

Under standard conditions, water freezes at

• 0°C

• 10°C

• 20°C

• 32°C

Molecular motion stops at

• 212°F

• – 32°F

• – 460°F

• 0°F

One British thermal unit will raise the temperature of

• 1 gallon of water 1°F

• 1 pound of water 1°F

• 1 pound of water 1°K

• 1 gallon of water 1°C

In which direction does heat flow?

• From a cold substance to a cold substance

• From a cold substance to a warm substance

• From a warm substance to a warmer substance

• From a warm substance to a cold substance

Heat transfer from molecule to molecule is known as

• radiation.

• convection.

• conduction.

• evaporation.

An increase in sensible heat causes

• a higher thermometer reading.

• a lower thermometer reading.

• no change of the thermometer reading.

• ice to melt.

Latent heat causes

• a higher thermometer reading.

• temperature to rise.

• a change of state.

• temperature to fall.
