A star is a self luminous astronomical object and shines due to internal radiation from the enrgy sources. All stars are held together by their own gravity called Gravitational force.

Yes... so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set.. and so whenever my interrupt occurs depending upon priority it will be serviced.. also the ISR address for all interrupts will be same ie 0024H..

Interrupt via trap is nonmaskable, so it will be serviced immediately.

Processes that require or give off heat will be limited to changes of state, known as phase changes, and changes in chemical constitution, or chemical reactions. Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing.

An exothermic process is one that gives off heat, which is transferred to the surroundings. An endothermic process is a reaction which heat has to be supplied to the system from the surroundings.

Here in all the given options, heat is taken away from them to change there phase. 

Liquid to Solid --- Freezing

Gas to Liquid --- Condensation

Gas to Solid --- Deposition 

are all examples of exothermic processes.
