(a)
Interpretation:
The difference between sample of gas and sample of liquid should be determined when the sample is transferred from one small container to a larger one.
Concept Introduction:
The characteristics of gases and liquids are:
- Liquid has definite volume but indefinite shape whereas the gas has indefinite volume and shape.
- Liquid has more density in comparison to gas but less than solid.
- Liquid has small compressibility in comparison to gas but larger than solid.
- Liquid has small thermal expansion in comparison to gas (moderate) but larger than solid.
(a)
Answer to Problem 5.1P
The volume of gas increases whereas the volume of liquid will not change when the gas is transferred from one small container to large container.
Explanation of Solution
The volume of gas changed with pressure whereas the volume of liquid is not changed with the pressure. When the gas is transferred from one small container to large container then the pressure decreases and the volume of the gas increases whereas there is no effect in the volume of liquid.
(b)
Interpretation:
The difference between sample of gas and sample of liquid should be determined when the sample is heated in an expandable container, but there is no change of state takes place.

(b)
Answer to Problem 5.1P
The volume of gas increases whereas the volume of liquid will not change when the gas is heated in an expandable container but no change in state takes place.
Explanation of Solution
When a gas is heated, its volume will increases 50 to 100 times greater than the liquid at constant pressure. Therefore, when the gas is heated in an expandable container,the volume of the gas increases whereas the volume will not change significantly.
(c)
Interpretation:
The difference between sample of gas and sample of liquid should be determined when the sample is placed in a cylinder having piston, and force is applied externally.

Principles of General Chemistry
- he following demonstration takes place in a two-step process: rst, solid calcium carbide (CaC2j)reacts with liquid water to produce acetylene gas (C2H2)and aqueous calcium hydroxide. Second the acetylene gas produced is then ignited with a match, causing the combustion reaction of acetylene with oxygen gas to produce gaseous carbon dioxide and gaseous water. Write the balanced equations for each reaction that is occurring, including all phases. If a 100.0gsample of calcium carbide (CaC2)is initially reacted with 50.0gof water, which reactant is limiting? Now imagine that the final gases produced are collected in a large bulkier and allowed to cool to room temperature. Using the information from part b ( l00.0gof Cec2reacting with 50.0gof H2O), how many liters of carbon dioxide gas were produced in the balloon at a pressure of 1.00atm and 25C?arrow_forwardHow many grams of water at 0C will be melted by the condensation of 1 g of steam at 100C?arrow_forward
