O2(g) effuses at a rate that is times that of br2(g) under the same conditions.

Oxygen gas effuses at a rate that is 2.236 times that of bromine gas under the same conditions.

Explanation:

Graham's Law:

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

We are given:

Molar mass of oxygen gas= 32 g/mol

Molar mass of bromine gas = 160 g/mol

By taking their ratio, we get:

Oxygen gas effuses at a rate that is 2.236 times that of bromine gas under the same conditions.

lol for the pointsss

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
