Suppose you have equal masses of water, ethanol, and oil (in separate containers). You heat each one from 26 °C to 81 °C. Which one requires the most heat? a. Oil
b. Ethanol
c. Water

c. Water

Explanation:

Heat capacity can be defined as the physical property of the matter. It is the amount of heat which is required to produce a unit change in the temperature of the material.

Water requires more amount of energy per gram of the liquid to change its temperature as compare to any other liquid like ethanol and oil. Ethanol is a volatile liquid so it will require less heat to boil but heat capacity of oil will be more than the oil. The heat capacity of water will be the highest, and it will require more heat.

d.) circle motion requires a force to give it a centripetal acceleration.

that's what i got you can count the number of atoms
