Question

The amount of energy required to raise the temperature of one kilogram of water by one degree Celsius is a:

Select one:
a. Calorie
b. Joule
c. Kilocalorie
d. Measure of density
e. None of the above are correct

Answer 1

c

Step-by-step explanation:

One kilocalorie (1 kcal or 1000 calories) is the amount of heat (energy) needed to raise the temperature of one kg of water by one degree Celsius (°C).

Answer 2

The energy required to raise the temperature of one kilogram of water by one degree Celsius is known as a kilocalorie, which is equivalent to 1,000 scientific calories or approximately 4,184 joules.

Step-by-step explanation:

The amount of energy required to raise the temperature of one kilogram of water:

The amount of energy required to raise the temperature of one kilogram of water by one degree Celsius is a kilocalorie or a Calorie (with a capital C). In scientific contexts, energy is typically measured using the SI unit of energy, which is the joule. One kilocalorie is equivalent to the amount of energy needed to raise 1 kg of water by 1°C and is equal to 1,000 calories (lowercase c) or approximately 4,184 joules.

The amount of energy required to raise the temperature of one kilogram of water by one degree Celsius is a kilocalorie. Historically, energy was measured in units of calories. A calorie is the amount of energy required to raise one gram of water by 1 degree Celsius. However, in the context of raising the temperature of one kilogram of water, the unit used is the kilocalorie. The kilocalorie (kcal) is commonly used in quantifying food energy content.

Therefore, the correct answer is kilocalorie.
