Question

Difference between Joule and calories!​

Answer 1

$\ \ \★ \: \: \Answer \: :-$

• Energy is the ability to do work. The energy can be measured using multiple units. Calorie and Joule are the units of energy. The relation between calorie and joule is proportionate. This implies any change in Calorie will change its equivalent value in Joules.

• a calorie is the unit of energy.
• Calorie or kilocalorie is the unit of energy = 1000 calories.
• Joule is the unit of energy
• Kilojoule is the unit of energy = 1000 joules.

Calorie - Joule

1 - 4.184

20 - 83.68

30 - 125.52

40 - 167.36

Answer 2

Question:

Difference between Joule and calories!

Answer:

Joule- It is the SI unit for energy, work and heat, it is defined as the work required to exert a force of one newton for a distance of one metre.

W = Force x Displacement

Hence, its unit is is also known as Newton-metre.

It is also equal to the energy supplied or released by 1 watt of power for a duration of one second.

It is denoted by J

Calorie - It is non-SI unit of energy which equals to approx 4.2 joules. It is the amount of energy needed to raise the temperature of 1 gram of water by 1 °C.

It is denoted by cal

1 Calorie = 4.2 Joules.
