Answer:
619.2 °C
Explanation:
Given data:
Initial volume of gas = 736 mL
Initial temperature = 15°C
Final volume = 2.28 L
Final temperature = ?
Solution:
First of all we will convert the temperature into kelvin and mL into L.
Initial temperature = 15°C (15+273 = 288 k)
Initial volume of gas = 736 mL × 1 L/1000 mL = 0.736 L
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
0.736 L / 288 k = 2.28 L / T₂
T₂ = 2.28 L× 288 k/0.736 L
T₂ = 656.64 K /0.736
T₂ = 892.2 K
Kelvin to °C:
892.2 K - 273.15 = 619.2 °C
