Answer:
the covalent molecule has OA.A
Decrease in temperature is -126.0°C
<u>Explanation:</u>
Using Charles law we can set up the equation as,
V₁/T₁ = V₂/T₂
(2.00 L) / 294.0 K) = (1.00 L) / (x)
cross multiply to get:
2x = 294
2x/2 = 294/2
x = 147.0 K
Now kelvin is converted into Celsius by subtracting 273 from 147 as,
147 - 273 = -126°C
Boyle's law gives the relationship between pressure of a gas and volume of gas.
It states that at constant temperature, pressure of gas is inversely proportional to volume of gas.PV = k
where P - pressure V- volume and k - constant
P1V1 = P2V2
since the gas occupies the volume of the container, volume of gas is taken as volume of container.
100kPa x 5.0 L = 50 kPa x V
V = 10.0 L
Answer is C.
