NWEA Science Practice Test 8

Front

What is mass?

Back

The amount of matter in an object.

Front

What does a balance measure?

Back

A balance measures the mass of an object by comparing it to known weights.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is.

Front

What unit is temperature commonly measured in?

Back

Temperature is commonly measured in degrees Celsius (°C) or degrees Fahrenheit (°F).

Front

How can you compare the mass of two objects using a balance?

Back

You can compare the mass of two objects by placing them on opposite sides of the balance and observing which side is lower.

Front

What does it mean if two objects have the same reading on a balance?

Back

It means that the two objects have the same mass.

Front

What happens to the temperature of water when it is heated?

Back

The temperature of water increases as it absorbs thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter.

Front

What is the relationship between mass and temperature in water?

Back

The mass of water does not directly affect its temperature; two bodies of water can have the same temperature regardless of their mass.

Front

What is the freezing point of water in degrees Celsius?

Back

The freezing point of water is 0° C.
