Answer» oflask containing tea is SHAKEN vigorously. Considering tea as a system (a) has heat been added to tea? (b) has work been done on it? (c) has its internal energy changed? (d) does its temperature rise?Answer : a. No , heat is not transfered from the surrounding.i.e. d Q = 0b. YES , work is done in shaking against the VISCOUS force .i.e. d W = - ve .c. Yes , internal energy of tea increases , ASD U = d Q - d Wd U = + ve [ d Q = 0 and d W = - ve ]d . Yes the temperature of tea rises due to increase in internal energy.
