What kind of energy is the heat energy?
thermal energyAnswerHeat describes energy in transit between a warmer body to and a cooler body, and is expressed in joules.
What energy changes occur when water freezes?
When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as: reactants --> products + energy
What is the movement of energy from warmer object to a cooler object?
the movement of energy from a warmer object to a cooler object is called heat transfer
Are energy and heat synonymous concepts?
Heat is a form of energy. Therefore they are not synonymous as whilst all heat is energy, not all energy is heat.
What is energy expressed in?
joules (J)
What is expressed in unit of calories or btu?
heat energy
Is calorie a noun?
Yes, it is a noun. It is a unit of energy, often expressed as heat, or as the energy value of food.
What kind of energy is the heat energy?
thermal energyAnswerHeat describes energy in transit between a warmer body to and a cooler body, and is expressed in joules.
What is the relation of the molar heat of fusion to the molar heat of vaporization?
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
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.
What are the units specikfic heat is commonly expressed in?
Specific heat capacity is the heat capacity per unit mass, and is expressed as
What similar between temperature and thermal energy?
In practical terms, temperature measures heat and heat measures the thermal energy of a system. In meteorological systems, for example, temperature, as an indirect measure of heat energy), reflects the level of sensible thermal energy of the atmosphere. Such measurements utilize thermometers and are expressed on a given temperature scale, usually Fahrenheit or Celsius. they are both related to heat.

What is tharmal energy in a scentence?
Energy has many different forms. A few of the most commonly thought of forms are electricity, thermal, and kinetic. Thermal Energy is energy expressed through a changing (usually upwards) in the temperature as heat.
What is a exotermic reaction?
An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation:reactants → products + energy

How are heat and work similar?
Heat and work are both expressions of energy. Usually it is a transfer of energy. Both are measured with energy units: Joule, for example, but Work is often expressed as a force multiplied by a distance, such as Newton meter, or foot pound. This comes from how we calculate the amount of work done.
