				   expansion of gases-variation with pessure

										Dear   vishal chintalapati,
1) for isobaric with no pressure change the volumetric thermal expansivity, which we denote βp, is:
$PV = nRT \,$ $\ln\left(V\right) = \ln \left(T\right) + \ln\left(nR/P\right)$ $\beta_p = \bigg(\frac{1}{V} \frac{dV}{dT}\bigg)_p = \bigg(\frac{d(ln V)}{d T}\bigg)_p = \frac{d(ln T)}{d T} = \frac{1}{T}$2) adibatic equation where temparature is constantPV^γ =ConstantThanksRathod ShankarIIT Bombay

 Tapas Khanda 5 months ago

Diagram is not required to solve this question. You can directly use the formula to find range : R = (v^2/g)*sin2Q Maximum height reached, H = v^2*sin^2Q/2g So, 25 = 40^2*sin^2Q/(2*9.8) So,...
