The temperature in degree celsius to which the gas was heated is calculated using the Charles law formula
that is V1/T1 =V2/T2
V1=88.2 ml
T1=35 +273 = 308 K
V2=123 ml
T2=?
by making T2 the formula of the subject T2=V2T1/V1
=(123 ml x308 k)/88.2 ml =429.5 K
in degree celsius = 429.5 -273= 156.5 degree celsius

Subsoil is the layer of soil under the topsoil on the surface of the ground.
Answer:
1.15 atm
Explanation:
According to Dalton's law of partial pressures, the total pressure is the sum of all the partial pressures of the gases present in the mixture.
Therefore we have:
Total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide
We were given the following:
Total pressure = 2.45 atm
Pressure of oxygen = 0.65 atm
Pressure of carbon monoxide = x
Pressure of carbon dioxide = 0.65 atm
Therefore:
2.45 = x + 0.65 + 0.65
2.45 = x + 1.3
x = 2.45 - 1.3
x = 1.15 atm
