Answer : The new pressure of gas will be, 25.176 kPa

Solution :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T

or,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1 = initial pressure of gas = 29.4 kPa

P_2 = final pressure of gas = ?

T_1 = initial temperature of gas = 75^oC=273+75=348K

T_2 = final temperature of gas = 25^oC=273+25=298K

Now put all the given values in the above equation, we get the final pressure of gas.

\frac{29.4kPa}{348K}=\frac{P_2}{298K}

P_2=25.176kPa

Therefore, the new pressure of gas will be, 25.176 kPa

<span>To solve this we assume that the gas inside the balloon is an ideal </span>gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant volume pressure and number of moles of the gas the ratio of T and P is equal to some constant. At another set of condition, the constant is still the same. Calculations are as follows:

 

T1/P1 = T2/P2

P2 = T2 x P1 / T1

P2 = 25 x 29.4 / 75

P2 = 9.8 kPa

2. Which energy source is considered a non-renewable resource?
Keith_Richards [23]

Answer:

The answer is D

Explanation:

Although natural processes continually form fossil fuels, such fuels are generally classified as non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made. ... The use of fossil fuels raises serious environmental concerns.
