The volume of a gas is increased from 0.5 L to 4.0 L while the temperature is held constant. The pressure of the gas will go fro

AVprozaik [17]

From Boyle's law the volume of a fixed mass of a gas is inversely proportional to the pressure at a constant absolute temperature. Thus; K = PV Hence; P1V1 =P2V2 0.5 × 24 = 4× P2 P2 = 12/4 = 3 atm Therefore; the pressure will go from 24 atm to 3 atm

The specific heat of lead is 0.0380 cal/g·°C. If 47.0 calories of energy raised the temperature of a lead sample from 28.3°C to

ollegr [7]

Answer:

Mass of lead, m = 687 g

Explanation:

The expression for the calculation of the enthalpy change of a process is shown below as:-

$\Delta H=m\times C\times \Delta T$

Where,

$\Delta H$ is the enthalpy change

m is the mass

C is the specific heat capacity

$\Delta T$ is the temperature change

Thus, given that:-

Mass = ?

Specific heat = 0.0380 cal/g°C

$\Delta T=30.1-28.3\ ^0C=1.8\ ^0C$

Heat added = 47.0 calories

So,

$47.0=m\times 0.0380\times 1.8$

Mass of lead, m = 687 g
