What are the SI units for heat?
The SI unit for heat is the joule (J). Additionally, the calorie (cal) is a commonly used non-SI unit for heat, where 1 calorie is equivalent to 4.184 joules.
How many kilocaclories of heat does the operation of a 1190 watt hair dryer produces each second?
Watts means joules per second. The device uses 1190 joules of energy every second; most of that will be converted to heat. It is best to use SI units most of the time; in this case, joules rather than calories for energy. However, if you want to convert that, 1 calorie = 4.184 joules; thus, you can divide the number of joules by 4.184 to convert it to calories.
What is the heat equivalent to 4200 joules?
4200 joules is equivalent to 1000 calories, or 1 kilocalorie (kcal).
The rate of heat transfer is measured in joules why?
The rate of heat transfer is measured in joules per second (or watts) because heat is a form of energy and joules is the unit of energy in the International System of Units (SI). By measuring heat transfer in joules, we can quantify the amount of energy being transferred between two systems per unit of time.
Express 60.1 cal of energy in units of joules?
60.1 calories is equivalent to approximately 251.5 joules.
What is the unit if he energy used in physical science and feed science?
A Joule is the SI unit of energy. It is equal to 1 Newton force, multiplied by 1 meter.The calorie is a heat energy unit. Equal to approx 4.184 Joules. In food Calories, is actually equivalent to a kilocalorie (1000 calories, or 4184 Joules).
What are the SI units for heat?
The SI unit for heat is the joule (J). Additionally, the calorie (cal) is a commonly used non-SI unit for heat, where 1 calorie is equivalent to 4.184 joules.
What is the unit of heat measure?
Joules(J).
What is unit of heat reaction?
calories or joules
What is the unit of measure for specific heat?
it is in joules. 03o
Is the unit of measure for specific heat?
it is in joules. 03o
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

4200 joules is equivalent to 1000 calories, or 1 kilocalorie (kcal).
What is unit is thermal energy?
BTU's or calories are directly related to the heat capacity of a substance or the heat produced in a reaction. All energy can be expressed in Joules, and for heat the relation is 4.2 Joules per calorie, this is called the mechanical equivalent of heat.Thermal energy is measured in joules (j).1 calorie = 4.2 JoulesAnswerIn SI, all forms of energy are expressed in joules(J).The British Thermal Unit (BTU) is an imperial unit for energy, rarely used anywhere outside the United States. The calorie is an obsolete (cgsA) unit despite being used (kilocalories) to some extent in the food industry.The terms, 'heat energy' and 'heat capacity' are both obsolete, having been replaced with 'internal energy' and 'specific heat capacity' (which is expressed in joules per kilogram kelvin).Work and heat are both described as energy in transit, and measured in joules.
