Water heating up slowly on the stove is an example of
A
adhesion
B
cohesion
C
high heat capacity
D
surface tension
Explanation: 

Detailed explanation-1: -Heat capacity is related to a substance’s ability to retain heat and the rate at which it will heat up or cool. For example, a substance with a low heat capacity, such as iron, will heat and cool quickly, while a substance with a high heat capacity, such as water, heats and cools slowly.

Detailed explanation-2: -Heat Capacity Definition Heat capacity is thus an inherent property of a substance. For example, water has an extremely high heat capacity of 4184 J per kilogram. This implies that 4184 J of heat energy is needed to raise the temperature of water by 1 Kelvin (or 1 Celsius).
