The sign's glass absorbed 25466.7 J
<h3>Further explanation</h3>Given
The temperature of glass : 23.5 °C to 65.5 °C
mass = 905 g
the specific heat capacity = 0.67 J/g °C
Required
Heat absorbed
Solution
Heat absorbed by sign's glass can be formulated :
ΔT=65.5 - 23.5 = 42
Answer: The pressure required is 0.474 atm
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
The equation is,
where,
= initial pressure of gas = 1.0 atm
= final pressure of gas = ?
= initial volume of gas =
= final volume of gas =
(
Now put all the given values in the above equation, we get:
The pressure required is 0.474 atm
