Water vapor from your breath on a freezing night
Ice on a pond
A snowball held in your gloved hand

"These windows must be really thin. I can feel the cold coming right through them."

What concept does the phrase “I can feel the cold coming right through them” refer to?

Heat
Thermal energy
Temperature
Change of state

You receive a text message from your lab partner during vacation. She texts you the following message:

"4YEO. Having a gr8 time! It is 85 here, and swimming every day. L8r."

Which of the following statements is correct regarding the content of your lab partner’s text referring to the number 85?

She is referring to the temperature, measured in Fahrenheit
She is referring to the temperature, measured in Celsius
She is referring to the heat, measured in Fahrenheit
She is referring to the heat, measured in Celsius

The following photograph shows a transparent pot of boiling water.

When you grab the handle to left the pot from the stove, you notice the handle is very warm. What is the best description of how the handle became warm?

Conduction of thermal energy through the water into the glass material of the pot
Radiation of thermal energy through the glass material of the pot
Convection of thermal energy through the glass material of the pot
Conduction of heat through the glass material of the pot

As you move close to a campfire, you notice the air seems warmer the nearer you get to the fire. Without touching it, you can tell that the fire is quite hot compared to its surroundings.

Which scientific concept allows you to feel that something is hot without touching it?

Radiation
Convection
Conduction
Reverse conduction

On a sunny summer day, why does a white car with a light-coloured interior stay cooler than a black car with a dark-coloured interior?

Solar radiation reflects off the lighter colours, away from the car, keeping the car cool
Solar radiation reflects off the darker colours, away from the car, keeping the car cool
Solar radiation is absorbed into the lighter colours, keeping the car cool
Solar radiation is absorbed into the darker colours, keeping the car cool

What type of radiation is associated with heat?”

Infrared
X ray
Gamma ray
Ultraviolet

Which scientific term is "the measure of the average kinetic energy of all the particles in a sample of matter"?

Temperature
Heat
Thermal energy
Radiation

Which has a greater thermal energy, a cup of 50°C water, or a bathtub of 50°C water?

The bathtub, since there are many more molecules, and thermal energy measures the total energy of the particles present
The bathtub, since there are many more molecules, and thermal energy measures the average energy of the particles present
The cup, since there are many more molecules, and thermal energy measures the total energy of the particles present
The cup and the bathtub are equal, since thermal energy measures the average energy of the particles present, and the average energy in both cases is 50°C
