Question

Any two gases, at the same temperature and pressure, of equal volumes contain the same number of molecules.

Select one:

True

False

Boyle's Law represents a relationship between pressure and volume. These variable are directly proportional.

Select one:

True

False

Dalton's Law of Partial Pressures states that each gas exerts different pressures if combined into a container with other gases.

Select one:

True

False

he unit of mmHg for pressure was developed by Torricelli using the mercury barometer.

Select one:

True

False

Answer 1

1.

the first statement is called avagadro's law

it is true

n = no fomoles = PV/T

if these three terms are equal obviously moles is equal

if moles is equal molecules are also equal.

2.

Boyle's Law represents PV = constant

so both are inversly propotional relation ship

so given statement False

3.

according to the Daltons law same pressure

but given as different pressure

so it is also False

4.

yes mmHg was developed based on the mercury barometer

answer is true
