Verified step by step guidance

Understand the concept of specific heat capacity: The specific heat capacity of a substance is the amount of energy required to raise the temperature of one gram of the substance by 1°C. For water, this value is 1 calorie per gram per degree Celsius.

Identify the given values: In this problem, we are dealing with 1 gram of water and a temperature change of 1°C.

Apply the formula for heat energy: The formula to calculate the heat energy required is Q = m × c × ΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Substitute the known values into the formula: Here, m = 1 gram, c = 1 calorie/gram°C, and ΔT = 1°C.

Calculate the energy required: By substituting the values into the formula, you can determine the amount of energy needed to raise the temperature of 1 gram of water by 1°C.
