IN the old school calorie is used as the unit of heat energy
Now in SI system, joule has taken that place
1cal = 4.18 J
Heat is molecular motion; the units are BTU and calories.
Heat is molecular motion; the units are BTU and calories.
You can use the same units (energy units) for both.
The total energy input is 100 units. If 20 units are used for light energy and 30 units for sound energy, then the remaining energy would be 100 - 20 - 30 = 50 units. Based on the principle of conservation of energy, this remaining energy would likely be converted mainly into heat energy.
No. Those are units of temperature. Heat is measured in units of energy, such as the joule.
Heat energy is most commonly measured in units of calories or joules.
Heat is also a type of energy, so energy units would be used in both cases. The standard (i.e., international) unit for all sorts of energy is the joule.
Heat energy is typically measured in joules (J) or calories (cal). Degrees Celsius and degrees Fahrenheit are units of temperature, not energy.
If 20 units are used for light and 30 units are used for sound, then a total of 50 units are used for those two purposes. This means 50 units are left to be converted into heat. So, the number of units of electric energy converted into heat is 50.
Fahrenheit (°F), Celsius (°C), and Kelvin (K)
The word "heat" as used in physics refers to heat energy, so it is logically measured in units of energy. The international unit for energy is the joule. Heat energy is sometimes still measured in the old-fashioned unit "calorie" instead.
In SI, all forms of energy are measured in joules.
