The kinetic theory of gases confirm that the volume occupied by gas molecules will be directly proportional to the temperature of the molecules and inversely proportional to the pressure of the molecules. We can consider the moles to be n = 1. Then, the equation for the gases will be
PV = nRT
Here, P is the pressure, V is the volume, R is the gas constant and T is the temperature.
So, P = 523 Torr, T = 7.50 °C = 7.50+273.15 = 280.65 K and the gas constant R = 62.363 Torr L mol⁻¹K⁻¹.
Filling in the blank, this is an example of <u>chemical weathering</u> which happens <u>to rocks</u> overtime.
Explanation:
Chemical weathering occurs when rocks are disintegrated by chemicals.
Rain water becomes acid rain when it reacts with carbon dioxide in the atmosphere (to form carbonic acid, HCO3).
When acidic rainwater falls and stays on rocks, chemical reactions take place with the minerals present in the rock, causing the rock to weather.
Areas with immense carbon dioxide and sulphur dioxide pollution increases rain water acidity, which in turn causes moisture in the atmosphere to dissolve these gases and produce acid rain.
Carbon dioxide is a gas because the particles surrounding it are more spread out and free from each other. Water is a liquid because the particles are partially spread out and have a medium space to move around. And due to the room temperature, salt's particles can either be hot and move rapidly, or be cold and not move rapidly.
