How many times is the air density in winter at a temperature of t1 = –23 ° C, more than the air density

How many times is the air density in winter at a temperature of t1 = –23 ° C, more than the air density in summer at a temperature of t2 = 27 ° C. The air pressure is constant.

To calculate the ratio of air density in winter to air density in summer, we use the formula: k = ρz / ρl = (P * M / (R * Tz)) / (P * M / (R * Tl)) = T / Tz.

Variables: T – abs. air temperature in summer (T = 300 K (27 ºС)); Tz – abs. air temperature in winter (Тз = 250 К (-23 ºС)).

Let’s make a calculation: k = Tl / Tz = 300/250 = 1.2 p.

Answer: The air density in winter is 1.2 times higher.
