Question:
A spherical black body is kept at constant temperature thermal equilibrium T and by supplying heat from some source. It is covered by another spherical surface which is also a black body (a very thin surface of radius almost equal to the previous one). Find the temperature at which...
A monatomic ideal gas undergoes a process in which the ratio of P to V at any instant is constant and equals to 1.
What is the molar heat capacity of the gas?
(A) 4R/2
(B) 3R/2
(C) 5R/2
(D) 0
If two plates of area A and separation d contain liquid in between with angle of contact 0 degrees, then what is the amount of force required to pull the two plates apart?
How do we derive this??
Whether rotation is possible or not depends on the angle of the inclined plane.
If you observe from the frame of the forward point of contact of block, then the torque will be provided by mgsinQ and normal reaction...in this case, friction does not matter...whereas if you observe from the frame...
can someone please tell me what actually is lattice enthalpy. Is it energy released when one mole of bonds are broken or the energy released when one of an ionic compound is broken into the constituents? So do we write U or 2U in the born habber cycle of MgCl2?
Is an adiabatic process isothermal also?
Can anyone please tell me if it is necessary for an adiabatic process to be isothermal? Please explain with example.
