Lower

Due to the presence of ice crystals in nearly frozen liquid water, the density of water is

Joules, calories Both of these

Heat energy is measured in units of

Region of lower density, microscopic slush Both of these

Ice crystals in nearly frozen liquid water make up a

Is composed of open structured crystals

Ice has a lower density than water because ice

Lower its temperature a bit, raise its temperature a bit Either of these

If you wish to expand the volume of a sample of water at 4°C

Gases

In most cases, which expands more for comparable changes in temperature?

Different rates of expansion

It is important that the two metals that compose a bimetallic strip have

High specific heats

Materials composed of molecules that absorb large amounts of energy in the form of internal vibrations and rotations have

Lower

Microscopic slush in ice water tends to make water density

Long time in changing temperature

One of water's interesting thermal properties is that when heated it takes a relatively

Less than 30 degrees C

Place a 1-kilogram block of iron at 40°C into 1 kilogram of water at 20°C and the final temperature of the two becomes

Thermal equilibrium

The fact that a thermometer "takes its own temperature" illustrates

Low

The fact that desert sand is very hot in the day and very cold at night is evidence that the specific heat capacity of sand is relatively

Translational motion

The kind of molecular motion that mostly relates to the temperature of a substance is

High specific heat capacity

4 degrees C

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

The tomato sauce feels hotter than the dough

Tomatoes have a higher specific heat capacity than dough. This means that when you bite into a hot pizza

The motion used in measuring temperature, motion that carries a molecule from one place to another. Both of these

Translational motion is characterized by

Copper expands more than iron

When a bimetallic bar made of copper and iron strips is heated, the bar bends toward the iron strip. The reason for this is

Larger
