above shows a balloon full of gas which has a volume of 120.0ml at 300.0k assuming pressure remains constant , what is the voume
1 answer:
128 ml is the voume of the balloon if the temperature of the gas increases to 320.0k.
Explanation:
given that:
T1 (initial temperature) = 300K
V1 ( initial volume) = 120ml
T2 (final temperature) = 320 K
V2 (final volume) = ?
Pressure remained constant throughout the process.
From the equation
=
Since pressure is constant the equation will be:
=
V2 =
Putting the values in the above formula:
V2 =
= 128 ml
128 ml is the volume of the gas if temperature increases from 3OO K to 320k

Explanation:
A mixture is defined as the substance that contains two or more different number of substances that are physically mixed together.
For example, a mixture of air which contains oxygen, nitrogen and other gases.
A mixture in which solute particles are unevenly distributed into the solvent then it is known as a heterogeneous mixture.
For example, sand in water is a heterogeneous mixture.
A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.
A homogeneous mixture is a clear solution.
For example, salt dissolved in water is a homogeneous mixture.
A solution is defined as the substance in which two or more substances are mixed together.
A compound is defined as the substance that contains two or more different elements that chemically combined together in a fixed ratio by mass.
A element is defined as the substance that contains only one type of atoms.
For example, a piece of sodium element will contain only atoms of sodium.
Whereas a pure substance is defined as the substance which contains only one type of molecule or one type of atom.
For example, ,
etc are pure substances.
Thus, we can conclude that the terms which could be used to describe the given sample of air is as follows.
- pure chemical substance.
- heterogenous mixture.
- mixture.
