The vapor pressure of dichloromethane at 0 degrees Celsius is 134 mmHg The normal boiling point of dichloromethane is 40 degrees Celsius. Calculate the molar heat of vaporization?
To calculate the molar heat of vaporization, we can use the Clausius-Clapeyron equation: ΔHvap = -R * T * ln(P2/P1) Where: ΔHvap = molar heat of vaporization R = gas constant (8.314 J/mol*K) T = temperature difference in Kelvin (40°C + 273 - 0°C = 313 K) P1 = vapor pressure at lower temperature (134 mmHg) P2 = vapor pressure at higher temperature (760 mmHg, since boiling point is at atmospheric pressure) Plugging in the values, we have: ΔHvap = -8.314 * 313 * ln(760/134) = -8.314 * 313 * ln(5.67) ≈ -37.4 kJ/mol Therefore, the molar heat of vaporization of dichloromethane is approximately 37.4 kJ/mol.
What will be the temperature of co2 gas at 20 bar pressure if initially its temperature is 313 kelvin at 35 bar pressure?
To find the final temperature of CO2 gas at 20 bar pressure, you can use the ideal gas law formula: ( P_1/T_1 = P_2/T_2 ), where ( P_1 = 35 ) bar, ( T_1 = 313 ) K, and ( P_2 = 20 ) bar. Rearrange the formula to solve for the final temperature ( T_2 ) by substituting the values of pressure and temperature.

What planet shortest of revolution is 11 years and 313 days and why?
The planet with the shortest revolution period of approximately 11 years and 313 days is Neptune. This is because it is the eighth planet from the Sun and orbits at a much greater distance compared to the inner planets, resulting in a longer orbital period due to Kepler's laws of planetary motion. Neptune's eccentric orbit and gravitational interactions also contribute to its specific revolution time, marking it as one of the slowest orbiting planets in our solar system.
