Question

In terms of Charle’s law explain why -273°C is the lowest possible temperature?

Answer 1

• According to Charle's law, V_t=V₀ $\left[1+\frac{t}{273}\right]$
• At -273°C, V_t=V₀$\left[1-\frac{273}{273}\right]$ = 0
• Thus, The temperature of -273°C is called absolute zero. All gases liquefy or solidify before reaching this temperature.
• At this temperature, all molecular motion stops. However, this temperature is impossible to attain.
