The colour of the can affected its ability to absorb heat energy.
True (A)
Why do darker colors, like black, absorb more heat?
Why do darker colors, like black, absorb more heat?
Because they take in a wider range of wavelengths from the light source.
What do lighter colors, like white, do with most of the incoming radiation?
What do lighter colors, like white, do with most of the incoming radiation?
Reflect it instead of absorbing it.
Which can absorbed more heat energy, the black can or the white can?
Which can absorbed more heat energy, the black can or the white can?
Which can experienced a faster increase in temperature, the black can or the white can?
Which can experienced a faster increase in temperature, the black can or the white can?

What is Radiation?
What is Radiation?
The transfer of energy as electromagnetic waves or particles.
Color and Heat Absorption
Color and Heat Absorption
Darker colors absorb more heat because they absorb a wider range of wavelengths. Lighter colors reflect more heat.
Effect of Color on Temperature
Effect of Color on Temperature
Darker colors absorb more heat energy, causing a quicker rise in internal temperature compared to lighter colors.

Study Notes
- The color of a can affects its ability to absorb heat energy
- This is due to radiation and absorption principles in heat transfer
Color and Heat Absorption
- Darker colors, such as black, absorb more heat
- Black absorbs heat because they take in a wider range of wavelengths from a light source
- Lighter colors, such as white, reflect most incoming radiation instead of absorbing it
Experiment Results
- The black can absorbed more heat energy
- The internal temperature of the black can rose more quickly
- The white can reflected more heat
- The white can absorbed less energy and heated up more slowly
- The black can experienced a faster increase in temperature compared to the white can
