It is the enthalpy change associated with the condensation of gaseous positive and negative ion into a crystal
The distribution of particle speeds in an ideal gas at a given temperature.
Carnot cycle is composed of how many reversible processes?
All the energy we consume ultimately becomes
How much will the length of a 1.0 km section of concrete highway change if the temperature varies from -15˚C in winter to 41˚C in summer?
is the grand total of all energies inside a substance.
How much heat is necessary to raise the temperature of 0.80 kg of ethyl alcohol from 15°C of its boiling point 78.3°C?
It is the energy possesses by the system as a result of its elevation with respect to the gravitational acceleration of the earth.
A rigid tank contains a hot fluid that is cooled while being stirred by a paddle wheel. Initially, the internal energy of the fluid is 850kJ. During the cooling process, the fluid loses 550kJ of heat, and the paddle wheel does 200kJ of work on the fluid. Determine the final energy of the fluid. Neglect the energy stored in the paddle wheel
The volume of a definite quantity of dry gas is inversely proportional to the pressure provided the temperature remains constant
What is the Si unit for temperature?
A process by which heat is transferred through a material without a bulk movement of the material
is the transition of a given substance from the solid to the gas phase with no intermediate liquid stage
Consider a person standing in a breezy room at 22°C. Determine the total rate of heat transfer from this person if the exposed surface area and the average outer surface temperature of the person are 1.2 m^2 and 33°C, respectively, and the convection heat transfer coefficient is 6 W/m^2.ε=0.95 and σ=5.67×10-8 W/m^4-K^4
It is the mode of energy transfer between a solid surface and the adjacent liquid or gas that is in motion, and it involves the combined effect conduction and fluid motion
A Carnot heat engine receives 500KJ of heat per cycle from a high-temperature source at 600 °C and rejects heat a low temperature sink at 40°C. Determine the thermal efficiency of this Carnot engine.
The change in physical size of a substance when its temperature changes.
A stress which develops within an object when it attempts to expand or contract in response to a temperature changes, but cannot, due to being held rigidly in place
In order to use a substance to make a thermometer the substance must with a temperature change
_________ states that a constant pressure and temperature, the volume of a gas is directly proportional to the number of moles present
