❤️here is your answer my dear friend :-❤️
______________________
a) when one gram of boiling water at 100°c condense to water at 100°c there is no change of temperature and the energy transfered is given by latent heat of vaporisation of water which is equal to 2260 joules

(a) The energy transferred when 1 gm of boiling water at 100C condenses to water at 100C is equal to the latent heat of vapourisation of water which is equal to 2260 Joule
(b) mass of water (m) = 1g
(b) mass of water (m) = 1ginitial temperature (T1) = 0 c
(b) mass of water (m) = 1ginitial temperature (T1) = 0 cFinal temperature (T2) = 100 c
(b) mass of water (m) = 1ginitial temperature (T1) = 0 cFinal temperature (T2) = 100 cspecific heat of water (s) = 1cal / g-c
(b) mass of water (m) = 1ginitial temperature (T1) = 0 cFinal temperature (T2) = 100 cspecific heat of water (s) = 1cal / g-cheat energy transferred Q = ms (T2-T1)
(b) mass of water (m) = 1ginitial temperature (T1) = 0 cFinal temperature (T2) = 100 cspecific heat of water (s) = 1cal / g-cheat energy transferred Q = ms (T2-T1) Q = 1x1x(100-0)
(b) mass of water (m) = 1ginitial temperature (T1) = 0 cFinal temperature (T2) = 100 cspecific heat of water (s) = 1cal / g-cheat energy transferred Q = ms (T2-T1) Q = 1x1x(100-0) = 100 cal
(b) mass of water (m) = 1ginitial temperature (T1) = 0 cFinal temperature (T2) = 100 cspecific heat of water (s) = 1cal / g-cheat energy transferred Q = ms (T2-T1) Q = 1x1x(100-0) = 100 cal100 cal is the temperature
