What is the total mass (in kg) of water vapor in the air in the apartment?A liquid and a solid of the same substance coexist in a flask as shown in the diagram below. The system is allowed to come to room temperature, causing the solid to melt into a liquid. After the solid melts, how will the volume of liquid in the flask compare with the total volume of the liquid and solid that initially occupied the flask? Your answer should indicate if the volume increases, decreases, or does not change in volume and should include the reason for your answer. Assume that there is no evaporation.7. A methanol powered car produces CO₂ when it runs. Does that mean it is contributing to global warming? (A) No, if the methanol was produced from recently living biomass (B) Yes, if the methanol was produced from recently living biomass (C) Yes, if the methanol was produced from solar power (D) No, if the methanol was produced from natural gas. 8. The density of compressed natural gas is 60 grams per liter.
