Thermal Energy Quiz

What is temperature a measure of?

• The weight of molecules

• The size of molecules

• The average speed of molecules

• The color of molecules

What is an average?

• The middle number in a set of data

• A single number that summarizes a set of data

• The lowest number in a set of data

• The highest number in a set of data

How do you find the average of a set of numbers?

• Subtract the smallest number from the largest number

• Add all the numbers and divide by the number of numbers

• Divide the largest number by the smallest number

• Multiply all the numbers together

What does the average speed of molecules tell us about temperature?

• The temperature of the thing with slower molecules is the same

• The temperature of the thing with slower molecules is higher

• The temperature of the thing with faster molecules is lower

• The temperature of the thing with faster molecules is higher

Why are averages helpful?

• They tell us the exact value of each member in a group

• They make it difficult to compare groups of different sizes

• They are not helpful at all

• They allow us to compare groups of different sizes without having to think about each individual member of the groups

• average kinetic energy

• total energy

• specific heat

• average potential energy

The faster an object moves, the _____ kinetic energy it has.

• less

• same

• more

• none of the above

While baking a pizza or boiling water, the molecules in them move as they release heat, they are examples of thermal energy.

• True

• False
