<span>1.50 x 3.00 = V x 1.00 atm ( Boyle's law)
V = 1.50 x 3.00 / 1.00 = 4.50 L </span>
The amount of heat that is required to raise the temperature of a system is calculated by the expression:
Heat required = m Cp ΔT
Heat required = 500 g (1.0 calorie/gram °C) (10.0 <span>°C)
Heat required = 5000 calorie
The correct answer from the choices listed above is the second option.</span>
