joules Calories, btu's (British thermal units), and degrees. Depends what you're doing.
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
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).
You think probable to molar heat, expressed in J/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 degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heatand temperature change is usually expressed in the form shown below where c is the specific heat.
Urine doesn't create or excrete heat. It dissipates heat and it would be the value of the temperature and the volume of the urine probably expressed in "calories" of heat energy. For humans the urine exits the body at about 99 degrees, but the volume would be a variable.
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 of vaporisation is the amount of heat require to transform substance from liquid to gas state at constant temperature. Heat of vaporisation expressed in kJ/kg of substance.
