At what temperature will a fixed amount of gas with a volume of 175 l at 15 degrees celsius and 760mmhg occupy a volume of 198l at a pressure of 640mmhg?

T₂ = 274.5 K = 1.35 °C

Explanation:

Given: V₁ = 175 L, P₁ = 760 mmHg, T₁ = 15°C = 288.15 K (∵ 1°C=273.15 K)

V₂ = 198 L, P₂ = 640 mmHg, T₂ = ? K

To calculate T₂, we use the General Gas Equation:

Therefore, T₂ = 274.5 K = 1.35 °C

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
