<span>During an exothermic process [heat flows from the system to the surroundings]. Exo roughly translates to outside, and thermic refers to heat. Heat is released from a system to its surroundings during an exothermic reaction, so the system would actually feel warm to the touch. The opposite of this is called and endothermic reaction.</span>
Because the average of one measurement would yield to itself, which provides nothing new to us. We need at least two for average to be purposeful.
Answer:
(C) increases; decreases
Explanation:
Since the two quantities are inversely proportional, it means that an increase in one quantity results in a decrease in the value of the other quantity. More so, an increase in the separation distance causes a decrease in the force of gravity and a decrease in the separation distance causes an increase in the force of gravity.
Answer:
Light waves slow down as they travel from gas to solid.
Explanation:
The speed of light is often quoted with reference to a vacuum. Light travels fastest in a vacuum and in a gas.
When light travels through other media such as solids or liquids, the speed of light is decreased due to absorption and scattering of photons by molecules as well as remissions.
Hence the speed of light decreases from gas to solid.
