Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid.

Evaporation is the process by which a liquid changes into a gas.

Evaporation is the process by which a liquid changes to a gas.

Evaporation is the process by which a liquid turns into vapor.

Photosynthesis is the process by which plants absorb carbon dioxide (CO2) from the atmosphere and convert it into glucose.

Photosynthesis is the process by which plants absorb carbon dioxide and convert it into glucose and oxygen using sunlight.

Evaporation is the process by which a liquid turns into vapor.

Recycling is the process of converting waste materials into reusable materials.

Desorption is the process of removing adsorbed molecules from a surface.

Adsorption is the process where a gas or liquid forms a thin layer on a solid surface.

Viscosity is the measure of a liquid's resistance to flow.

The boiling point is the temperature at which a liquid turns into vapor.

The boiling point is defined as the temperature at which a liquid's vapor pressure equals the external pressure.

The melting point is the temperature at which a solid becomes a liquid.

The transition from a gas to a liquid is called condensation.

Sublimation is the process where a solid transitions directly to a gas without becoming a liquid.

Evaporation is the process of a liquid turning into gas below its boiling point.

Evaporation is the process where liquid turns into gas.

Sublimation is the process where a solid turns directly into a gas.

The term 'adsorption capacity' refers to the amount of solute that can be adsorbed per unit mass of adsorbent.

10 g of Na = 0.434 moles. 2Na + H2SO4 → Na2SO4 + H2. 0.434 moles of Na2SO4 = 0.434 * 142 g = 61.6 g.

23 g of Na = 1 mole. 1 mole of Na produces 1 mole of NaCl = 58.5 g.

23 g of Na = 1 mole. 1 mole of Na produces 1 mole of NaCl = 58.5 g.

1 mole of CO2 contains 1 carbon atom and 2 oxygen atoms, totaling 3 atoms.

C4H10 has 4 carbon atoms and 10 hydrogen atoms, totaling 14 atoms.

The total number of electrons is 36 (from Kr) + 2 (from 5s2) + 10 (from 4d10) + 5 (from 5p5) = 53.

The decomposition of CaCO3 produces CaO and CO2: CaCO3 → CaO + CO2. This results in 1 mole of gas (CO2) being produced.

The decomposition reaction is CaCO3 → CaO + CO2. This produces 1 mole of CaO and 1 mole of CO2, totaling 2 moles of gas.

The n=2 shell has 4 orbitals: 1s and 3p orbitals.

The total number of orbitals in the n=3 level is given by n^2 = 3^2 = 9.
