Question

Q14. Which of the following statements 'is incorrect', in reference to Charles Law: *
a The lowest hypothetical or imaginary temperature at which gases are supposed to occupy zero volume is called Absolute zero.
b For all gases, at any given pressure, graph of volume vs temperature (in celsius) is a straight line and on extending to zero volume, each line intercepts the temperature axis at – 273.15 °C.
c pressure remaining constant, the volume of a fixed mass of a gas is inversely proportional to its absolute temperature and the nature of curve obtained on plotting the graph between V and T is a rectangular hyperbola.
d for a fixed mass of a gas at constant pressure, volume of a gas increases on increasing temperature and decreases on cooling.

Answer 1

Answer:

B

Explanation:

According to Charles law, at constant pressure, for a given mass of a gas, the volume of the gas is proportional to its absolute temperature.

So, this means that the graph of volume v/s temperature is a straight line.
