How does styrofoam keep things cool?
Styrofoam is a good insulator because it is made up of 95% air. This trapped air prevents the transfer of heat energy, keeping things cool by slowing down the rate of heat transfer from the environment to the contents inside the Styrofoam container.
Why do different materials heat up at different rate?
Different materials heat up at different rates because of their unique properties such as density, specific heat capacity, and thermal conductivity. These properties determine how quickly a material can absorb, store, and transfer heat energy when subjected to a heat source. Materials with higher specific heat capacity or thermal conductivity will generally heat up more slowly than those with lower values.
How would the shape of an object affect the rate of change in temperature?
The shape of an object can affect the rate of change in temperature by influencing how heat is transferred. Objects with a larger surface area relative to their volume, like thinner or more spread out shapes, tend to cool or heat up faster as they can transfer heat more efficiently. Conversely, objects with smaller surface areas, like compact or thicker shapes, may take longer to cool or heat up due to reduced heat transfer efficiency.
What is the direct transfer of heat energy called?
conduction is the direct transfer of heat energy. It works like this:when two things to separate temperatures meet, then one cools down and the other heats up until they are both the same temperature.
The invisible heat from the sun is called?

A porcelain container used to heat things up in?
It is called a Crucible
What are the things that heat up your toast in the toaster called?
Those are called heating elements or toaster coils. They generate the heat needed to toast the bread by converting electrical energy into heat.
What conditions will increase the rate of evaporation?
Heat speeds up the rate of evaporation.
What were the benefits of the Bunsen Burner?
to heat things up, to hold test tubes while the get heated (mostly to heat things up)
How does presence of light affect the rate of decomposition?
light will produces heat which will speed up the rate of decomposition.

What do you call the heat given to or given up from a substance?
The heat given to or given up from a substance is called heat transfer.
What could be done to increase the rate of decomposition of CaCO3?
Just heat it up.
How could you increase the rate of dissolving of sugar in tea?
heat up the tea
How does color and heat energy work together?
What we perceive as color is electromagnetic radiation. As objects heat up, the frequency of the energy they radiate shifts and broadens which means that the color changes. The actual color is dependent on, among other things, the frequency of the vibration of the bonds in the molecules, so different things look different colors at the same temperatures. The rate at which heat radiates from an object is proportional to the 4th power of the absolute temperature, so if you double the temperature, you get 16 times the rate of radiated heat. The rate at which an object absorbs heat is also dependent on its color. A "black object" is one that absorbs all radiated energy that hits it.
Why does your ear heat up when it gets hit?
when tow things strike each other it get heat.
