The first law of thermodynamics is based on conservation of energy.
The process, in which there is no exchange of heat is called adiabatic process.
The internal energy of an ideal gas depends upon temperature only.
In an isothermal expansion the internal energy of an ideal gas remains constant.
ice point=0ᵒC=273K and steam point=100ᵒC=373K
When heat is added to a system, its entropy increases.
By increasing pressure the melting point of ice decreases.
Heat transmission is fastest in radiation process.
Wein's radiation law holds for smaller wavelength.
Planck's law of radiation holds for all wavelength.
Rayleigh Jean's law holds for longer wavelength.
At the mount, boiling point of water decreases due to decrease in pressure.
At equipotential surgace, all points have equal voltage so, work done will be zero.
Two parallel wires carrying currents in opposite directions repel each other.
The conductivity of an ideal dielectric is zero.
In a non uniform field, if a substance tends to move from the stronger to weaker parts of the field, then it is diamagnetic.
The electric current in a metallic conductor is due to the flow of free electrons only.
The specific resistance of a wire depends upon its material.
The resistance of a wire is doubled if its radius is halved and length is doubled.
A transformer converts low AC voltage into high AC voltage and vice versa.
Electric dipole moment of a non-polar molecule is zero.
