Question

of a gas has a pressure of 3.00 atm at 25°C. What would the gas pressure be at 52°C, if the volume remains constant

Answer 1

If the volume remains constant, then you use Gay-Lussac's Law stating that the pressure exerted by a gas is directly related to the temperature in Kelvin. So you use the formula \[P _{1} \div T _{1} = P_2 \div T_2\] First you convert your temperature into Kelvin. Then you insert your initial pressure and temperature. Then insert your second temperature and solve for P2. Do you need help beyond this point??
