Power is the rate of doing work, or of heat transfer, and is expressed in watts which is equivalent to a joule per second.
600 cannot be expressed in thousands of dollars because 600 is below 1,000 which is the minimum number to be expressed in thousands.
Repeating Decimal can be expressed exactly using what
An irrational number is one that can NOT be expressed as a fraction, with integer numerator and denominator. 3.8 CAN be expressed as such, namely, 38/10, so it is RATIONAL.
Rational numbers can be expressed as a terminating or repeating decimal.
Specific heat capacity is the heat capacity per unit mass, and is expressed as
The heat capacity depends on the mass of a material and is expressed in j/K.The specific heat capacity not depends on the mass of a material and is expressed in j/mol.K.
heat energy
Energy expressed as heat is the kinetic energy transferred between particles within a substance or between different substances due to a temperature difference. It is commonly measured in units such as joules or calories.
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).
Yes, it is a noun. It is a unit of energy, often expressed as heat, or as the energy value of food.
The amount of heat released / absorbed from a substance at constant temperature as you change state from liquid->solid / solid->liquid.
The heat released when 1 mole of a substance undergoes complete combustion is called the molar heat of combustion.
The latent heat of fusion is the amount of heat energy needed to change a substance from a solid to a liquid at its melting point. It is a characteristic property of each substance and is usually expressed in joules per gram.
Power is the rate of doing work, or of heat transfer, and is expressed in watts which is equivalent to a joule per second.
Heat transfer can be expressed in units of joules (J) or calories (cal). Another common unit for heat transfer is the British thermal unit (BTU) in some regions.
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.
