Question

or tell me how to do it

oops! its supposed to be: A sample of argon has a pressure of 1.059 atm at a temperature of 60.8 degC. Assuming that the volume is constant, at what temperature will the gas have a pressure of 1006.25 mmHg. Express your final answer in Kelvins.

Answer 1

Use the combined gas law. It is:

PV/T = PV/T

P = pressure
V = volume
T = temperature (in Kelvin; add 273 to the C temp. to get it in Kelvin)

Just plug stuff in and see what you get.

Answer 2

The gas law, P*V=k*T, where k=const. Here, V is also constant so P~T. Whatever the ratio of the pressures is, that will be the ratio of the temps.
