13. Mercury has one of the lowest heat capacities. If 257J of heat are added to 5500g of mercury,the mercury's temp will increas
NikAS [45]

Given:

257J of heat

5500g of mercury

increase by 5.5 degrees Celsius

Required:

Specific heat of mercury

Solution:

H = mCpT

257J = (5500g of mercury) Cp (5.5 degrees Celsius)

Cp = 8.5 x 10^-3 Joules per gram per degree Celsius

Helium gas in a cylinder is under 1.12atm pressure at 25.0C. What will be the pressure if the temperature increases to 37.0C?
Irina18 [472]

Answer:

p_2=1.17atm

Explanation:

Hello!

In this case, considering that the Gay-Lussac's law allows us to relate the temperature-pressure problems as directly proportional relationships:

\frac{p_2}{T_2} =\frac{p_1}{T_1} \\\\

Thus, for the initial pressure and temperature in kelvins the final temperature in kelvins, we compute the final pressure as:

p_2=\frac{p_1T_2}{T_1} \\\\p_2=\frac{1.12atm*310.15K}{298.15K}\\\\p_2=1.17atm

Best regards!
