Agas occupies a constant volume at 35.0 ⁰c and 97 kpa. what is the pressure of the gas when the temperature is increased to 75.0⁰c? show all work.

Gay-Lussacs law relates the pressure of gas with temperature when all the other conditions are kept constant. 
It states that for a fixed amount of gas, pressure of gas is directly proportional to temperature when the volume is constant.

where P - pressure, T- temperature and k - constant
temperature has been given in Celsius, we need to convert to Kelvin
Temperature in K = Temperature in Celsius + 273.15
1st instance  T1 = 35 °C + 273.15 = 308.15 K
                     P1 = 97 kPa
2nd instance T2 = 75 °C + 273.15 = 348.15 K
                      P2 - needs to be calculated using following equation 



P2 = (97 x 348.15)/308.15
P2 = 110.0 kPa

Sugar and water are chemically combined.(a solution is chemically combined while a mixture is mixed together without bonding the molecules)
