How many joules are in 55.2 calories?
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
Express 60.1 cal of energy in units of joules?
The mechanical equivalent of heat is 4.2 Joules/calorie, so 60.1 calories = 252.42 Joules
How much heat is generated by 1700 joules of work?
If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.
When 100 J of heat is added to a system that performs 60 J of work the thermal energy change of the system is?
If 60 Joules of mechanical energy is transformed to thermal energy without losses, the heat produced will be the equivalent of 60 Joules which is 14.3 calories (4.2 Joules per calorie)
What is thermal energy measured in?
Heat is measured in joules.
Suppose you want to heat 40kg of water by 20c How many joules of heat are required?
Energy = mass x specific heat capacity x change in temperature specific heat capacity of water = 4200 Joule per kilogram per degree Celsius Energy = 40 x 4200 x 20 = 3.36x106 Joules.
How many joules are in 55.2 calories?
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
Express 60.1 cal of energy in units of joules?
The mechanical equivalent of heat is 4.2 Joules/calorie, so 60.1 calories = 252.42 Joules
How hot is a joule?
The mechanical equivalent of heat is 4.2 Joules per calorie, so 4.2 Joules can heat 1 gram of water by 1 degree C.
What is the equivalent of 4200 milliliters in liters?
4200 millilitres is equivalent to 4.2 litres.
How much heat is generated by 1700 joules of work?
If all 1700 Joules of work get converted into heat, then, of course, you get 1700 Joules of heat.
How many joules are in 5.2 Calories?
162 calories is 678.2616 joules. For most purposes you don't need such accuracy, remember one calorie = 4.2 Joules. This is called the mechanical equivalent of heat, and is a useful number to memorize.
Why is water used as a coolant in car radiators?
Water is used as coolant in car radiators because it has high specific heat capacity of 4200 Joules. It has the highest specific heat capacity than any other substance. That is why it is used as coolant in car radiators
What is the heat of solution for barium chloride in joules?
103 joules
Suppose you want to heat 40g of water by 20c how many joules of heat are required?
334.8 Joules
When 100 J of heat is added to a system that performs 60 J of work the thermal energy change of the system is?
If 60 Joules of mechanical energy is transformed to thermal energy without losses, the heat produced will be the equivalent of 60 Joules which is 14.3 calories (4.2 Joules per calorie)
What is the measurement for specific heat?
The unit for specific heat is Joules/g-Kelvin or it can be Joules/g-Celsius J= Joules g= Grams C= Celsius
