The pressure on a fixed ma decrease lease, orremalon a fixed mass of a gas is tripled at constant temperature. will the volume increase remain the same? 5.35 at what pressure does the gas occupy a volume of 5 0: 37 calculate the boyle's law constant at a volume of 2 l.? charles's law - 5.41, 5.43, 5.45, 5.49, 5.51 5.41 state charles's law in words. 5.43 explain why the kelvin scale is used for gas law calculations 5.45 the temperature of a gas is raised from 25°c to 50°c. will the volume double if mass and pressure do not change? why or why not? 5,49 a balloon containing a sample of helium gas is warmed in an oven. if the balloon measures 1.25 l at room temperature (20°c), what is its volume at 80'c?
