Every quantity that is studied in science needs to be quantified and to quantify it must have a unit of measurement.
b and d.The amount of sugar or fat in foods is given in terms of grams. For example, the fat in potato chips is 35 grams. Alternatively, if the serving size is known, it is taken as a base to express the fat or sugar content as a percentage.kcal is not a measure of fat or a term used to describe the amount of sugar and fat in foods.
Hence, options 'b' and 'd' are incorrect.
c.Immersion heater, open coil heaters, fuel oil heaters, circulation heaters, thermal fluid vaporizers, air duct heaters, storage tank heaters, water heaters, glycol heaters, gas fired thermal fluid heaters are the different types of heating devices known. There is no such heating device called kcal.
kcal is not a heating device.Hence, option 'c' is incorrect.
a.Heat energy is usually measured in calories. If the number of calories involved is to the tunes of 1000s, then a unit of measurement call kilocalories is used. One kilocalorie is equivalent to 1000 calories. kcal is the abbreviated form for kilocalories.
kcal is a measure of heat energy.
Hence, option "a" is the correct option.
