At constant pressure increasing the temperature of a fixed amount of gas will do what

Naddika [18.5K]

Answer:

For a fixed mass of gas at constant pressure, the volume is directly proportional to the kelvin temperature. That means, for example, that if you double the kelvin temperature from, say to 300 K to 600 K, at constant pressure, the volume of a fixed mass of the gas will double as well.

Part A Which of the following statements about chemical formulas is FALSE? Which of the following statements about chemical form

statuscvo [17]

Answer: Option (a) is the correct answer.

Explanation:

Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.

For example, in $C_{7}H_{7}NO_{2}$ the subscripts present in it are 7, 7, 1, and 2.

A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.

Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
