An explorer in the mountains witnesses tea boiling at a certain °C. What is the atmospheric pressure? Estimate ΔHvap between two temperatures (°C).
An explorer in the mountains witnesses tea boiling at a certain °C. What is the atmospheric pressure? Estimate ΔHvap between two temperatures (°C).
Two metals are given with their boiling and melting points. Determine which has the larger surface tension and which is more volatile.
The air over an unknown liquid at a temperature (°C) has a total pressure (atm). A sample of x liters is collected. Volume (L), temperature (°C), and pressure (atm) of the remaining air is given. What is the vapor pressure?
Choose all that apply. A liquid’s vapor pressure (in mmHg)at a temperature (K) is given. The compound is placed in a container (mL) and put at a certain pressure (mmHg). If the container is reduced to a new mL, what happens?
Multiple part question asking for 2 or 3 of the following: ideal pressure in mmHg, pressure at equilibrium in mmHg and/or will all liquid evaporate? Vapor pressure (mmHg), temperature (K), grams and volume (mL) are given.
Two pressures and two temperatures (in K) are given. Determine the molar heat of vaporization.
The normal boiling point (K) and molar heat of vaporization are given for a liquid. Determine the new boiling point at a new pressure (atm).
Choose all that apply. A liquid’s vapor pressure (in mmHg)at a temperature (K) is given. The compound is placed in a container (mL) and put at a certain pressure (mmHg). If the container is reduced to a new mL, what happens?
Two temperatures (in °C) and two pressures are given. Determine the enthalpy of vaporization (ΔHvap).
The enthalpy of vaporization and normal boiling point are given. Determine how many kJ of heat (ΔH) are needed to evaporate or condense x kilograms. This solver works for both questions asking for evaporate the sample and questions asking to condense the sample.
