Suppose you have a box of atomic hydrogen, initially at room temperature and atmospheric pressure. you then raise the temperature, keeping the volume fixed. (a) find an expression for the fraction of the hydrogen that is ionized as a function of temperature. (you'll have to solve a quadratic equation.) check that your expression has the expected behavior at very low and very high temperatures. (b) at what temperature is exactly half of the hydrogen ionized? (c) would raising the initial pressure cause the temperature you found in part (b) to increase or decrease? explain. (d) plot the expression you found in part (a) as a function of the dimension- less variable t = kt/i. choose the range of t values to clearly show the interesting part of the graph.

Asmall electric heater, immersed in 80g of water in a calorimeter of 40j/k raises the temperature from 10.5 degree celsius to 25 degree celsius in 12 minutes. using the same apparatus with 50g of oil instead of water, it is found that the temperature of oil rises from 7 degree celsius to 27 degree celsius in 10 minutes. find specific heat capacity of the oil.
