The answer is number 4 or the exchange of energy with the surroundings. Calorimetry is a measurement of energy that is formed or absorbed in a certain process. The calorimeter is the instrument used in order to measure the energy. It is recommended that a calorimeter should be a closed system so as to measure precisely the energy and avoid or lessen the exchange of energy with the surroundings. Thus, comparing an open ceramic mug and an insulated mug with a lid, the greatest difference is the energy lost to the surroundings.

Answer:
D. As white light passes through a prism , it bends and separates into different colors
Explanation:
When light enters a prism, it experiences a phenomenon called 'refraction'.
Refraction occurs when light crosses the interface between two mediums with different optical density; when this happens, the light bends and also changes speed.
The angle at which the ray of light is refracted into the second medium depends on the optical density of the two mediums, but also on the wavelength of the light.
In particular, longer wavelengths (red color) are refracted the least, while shorter wavelengths (violet color) are refracted the most.
As a result, when white light (consisting of all the colors of visible light) enters into a prism, they different wavelengths are separated: therefore, white light separates into different colors.
So, the correct answer is
D. As white light passes through a prism , it bends and separates into different colors
Answer:
Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase noticeably.
