[单选题]
An ideal gas is enclos.m8gr8ts jsqv; i5zy/ed in a container of fixed volume. When the temperaturdh4/x e xoar:,e of the gas is/ aex,xorh4d : i$27^{\circ}C$ ts pressure is $p$. Calculate the pressure in the gas when it is heated to $54^{\circ}C$
A. $p$
B. 1.09$p$
C. 1.5$p$
D. 2$p$
参考答案: B
本题详细解析:
Temperature appears to be doubled; but that is using the celsius scale. Absolute temperature is not doubled. So, D is incorrect. Volume cannot change, since the container's volume is fixed. The number of moles cannot change since the gas is enclosed in the container. Hence, pressure is proportional to absolute temperature: $\frac{p_2}{p}=\frac{273+54}{273+27}⇒p_2=1.09p$.
