Answer:
No
Explanation:
If you heat the air inside a rigid, sealed container, then you are keeping it's mass and volume constant.
Then, Pressure of the container is directly proportional to the temperature.
Gay-Lussac's Law: This law states that the pressure of a given amount of gas when at constant volume is directly proportional to gas's absolute temperature in Kelvin.
So, if Kelvin temperature doubles, the air pressure in the container will also double.
The relationship between Celsius temperature and Kelvin temperature is not linear.
If becomes
, then
will become
.
i.e, it is increasing for sure, but doesn't double.
Answer:
49,736.84 kJ
Explanation:
1 L of gasoline has 0.70 kg
1,5 L of gasoline has x kg
1 L - 0.70 kg
1.5 - x
x = 0.7 *1.5 = 1,05 kg
1 mol of gasoline has 114 g
y mol of gasoline has 1050 g
1 mol - 114 g
y - 1050 g
y = = 9.21 mol
1 mol of gasoline has a combustion heat of 5400 kJ
9.21 mol of gasoline has a combustion heat of z
z = 5400 * 9.21 = 49,736.84 kJ
