What are kilojoules chemistry?
Keeping this in consideration, what are kilojoules?
kJ (kilojoules) is the Australian measure of how much energy people get from consuming a food or drink. Energy in food and drinks is measured by the number of kJ (kilojoules) it provides. kJ are similar to Calories: 1 kJ = 0.2 Calories (Cals) 1 Calorie = 4.2 kJs.
Also Know, what is the difference between kilojoules and calories? Essentially, the difference between calories and kilojoules is terminology - they're two different ways of measuring the energy contained in food and the energy we expend. You can convert calories to kilojoules by multiplying the calories by 4.2.
Also to know is, what are calories in chemistry?
A calorie is a unit of thermal energy equal to 4.184 joules or the amount of energy required to raise the temperature of 1 gram of liquid water 1°C at standard pressure.
How are kilojoules measured?
A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy used to be measured in Calories (Cal) and some countries still use those units. The conversions are as follows: 1 kJ = 0.2 Cal.
