The density of oxygen at N.T.P. is 16 g ...

The density of oxygen at N.T.P. is `16 g dm^(-3)`.To What temperature should it be heated at a constant pressure so that the density becomes `8 g dm^(-3)` ?

Text Solution

Verified by Experts

At constant pressure `rho_(1)T_(1) = rho_(2)T_(2)`
According to available data, `rho_(1) = 16 g dm^(-3), T_(1) = 273 K, rho_(2) = 8 g dm^(-3), T_(2) = ?`
`:. T_(2) = (rho_(1)T_(1))/(rho_(2)) ((16 g dm^(-3)) xx (273 K))/((8g dm^(-3))) = 546 K`.
