Ch 15 practice test

Aluminum has a higher specific heat capacity than iron. This means that for equal masses of aluminum and iron, the metal that heats more quickly when the same amount of heat is applied is

iron

The fact that desert sand is very hot in the day and very cold at night is evidence that sand has a

low specific heat capacity

Room temperature on the Kelvin scale is about

300 K

The temperature at the bottom of Lake Tahoe, high in the Sierra Nevada mountains in California at this moment is

4 degrees C

If the specific heat capacity of water were lower than it is, a hot bat would be

A shorter experience

Which of the following expands more when the temperature is increased? Equal volumes of

Helium

If the temperature of a sample of water at 4 C is slightly lowered it's volume

Increases

If you measure the width of an outdoor barn with a steel tape on a very cold day, your measured width will be

a bit long
