If the gas is compressed to a volume of 0.70 m³, and the absolute pressure is raised to a value of 0.80 x 10⁵ pa, the temperature will eventually reach 287.1°C.
Ideal gas equation: PV = nRT
where P is pressure, V is volume, n is moles of gas, R is the molar gas constant and T is the temperature in K.
Since n and R are constant, PV/T = constant
P1 = 0.200 x 10⁵ Pa, P2 = 0.800 x 10⁵ Pa

what is the change in potential energy of an energetic 64 kgkg hiker who makes it from the floor of death valley to the top of mt. whitney?
11,700 Joules are roughly lost from the hiker's energy stored. These are computed by adding the hiker's mass (64 kg), the elevation difference among both Death Valley & Mt. Whitney (2,400 m), and the lift force (9.8 m/s2).
Assessments must be made in the beginning to ascertain where far the climber is ascending. At 14,505 feet above sea level, Mount Whitney is indeed the tallest mountain there in continental United States. At 282 feet below sea level, Death Valley was its lowest place in North And south america. This indicates that the hiker is ascending an overall height of 14,787 feet.
Calculating the variation in potential electricity is produced following. Potentially energy is equivalent to something like an object's mass increases the speed caused by gravitation times the object's altitude. Therefore, the hiker's modification in energy potential can be measured:
(64 kg) * (9.8 m/s2) * (Change in Potential Energy) (14,787 ft)
9,424,912 kg/m2/s2 equals the change in potential energy.
