When a 2lb of brass at 212°F is dropped into 5lb of water at 35°F, the resulting temperature is 41.2°F. Find the specific heat of brass in Btu/lb-°F
Heat is transferred to a heat engine from a furnace at a rate of 92MW. If the rate of waste heat rejection to a nearby river is 45MW, determine the net power output and the thermal efficiency for this heat engine.
is the grand total of all energies inside a substance.
This law states that at constant temperature the volume of a sample of gas varies inversely with the pressure
Vapor pressure depends only on
is a measure of the average kinetic energy per molecule in a substance. a. movement
A process by which heat is transferred through a material without a bulk movement of the material
An idealized perfect absorber and perfect emitter of radiation
Convert the change of temperature from 20˚C to 30˚C to Kelvin scale
The change in physical size of a substance when its temperature changes.
It is the energy possesses by the system as a result of its elevation with respect to the gravitational acceleration of the earth.
It is the transfer of energy from the more energetic particles of substance to the adjacent less energetic ones as a result of interactions between the particles.
It states that if two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other
The volume of a definite quantity of dry gas is inversely proportional to the pressure provided the temperature remains constant
It states that energy can neither be destroyed nor created; it can only change forms
It is the energy emitted by the matter in the form of electromagnetic waves as a result of the changes in the electronic configurations of the atom or molecules
What is the amount of radiant energy received each second over each square meter that is at right angles to the sun’s rays at the top of the atmosphere?
This Law states that if a process can be written as the sum of several stepwise processes, the Enthalphy change the total process equals the sum of the Enthalphy changes of the Various Steps
