Explanation

Inhibitors are molecules that decrease the activity of enzymes, often by binding to a specific site on the enzyme.

Activators are molecules that increase the activity of enzymes, often by binding to a specific site on the enzyme.

Explanation

Linear thermal expansion of a solid depends on:

• Increase in temperature
• Original length
• Properties of the material

Explanation

The rate of evaporation can be increased by:

• Decreasing atmospheric pressure
• Increasing temperature
• Decreasing humidity
• Increasing the surface area of the liquid

Explanation

Evaporation occurs when molecules on a liquid's surface gain enough energy to escape into the air, and this can happen at any temperature, not just at boiling point.

It's a slow process at lower temperatures, but faster at higher temperatures.

Explanation

Latent heat of vaporization is the energy required to change a liquid into a gas (or vice versa) without changing its temperature.

Latent heat of fusion is the energy required to change a solid into a liquid (or vice versa) without changing its temperature.

Explanation

Latent heat of fusion is the energy required to change a solid into a liquid (or vice versa) without changing its temperature. 

Latent heat of vaporization is the energy required to change a liquid into a gas (or vice versa) without changing its temperature.

Explanation

The melting point of ice at normal atmospheric pressure is 0 °C (zero degrees Celsius).

Key Points:

• 0 K (zero Kelvin) is equivalent to -273.15 °C, which is absolute zero, the lowest possible temperature.
• 100 °C is the boiling point of water at normal atmospheric pressure.

Explanation

The boiling point is the temperature at which a pure liquid changes state from liquid to gas at standard atmospheric pressure.

Key Points:

• The melting point is the temperature at which a solid changes state to a liquid.
• The freezing point is the temperature at which a liquid changes state to a solid.

Explanation

Specific heat capacity is the thermal energy transfer required per unit mass to increase the temperature of a substance by 1°C (or 1 K).

It is a measure of how much heat energy a substance can absorb or release per unit mass per unit temperature change.

Explanation

Heat of vaporization is the amount of heat energy required to convert a substance from its liquid state to its gaseous state, without changing its temperature.

This energy is used to break the intermolecular forces between the molecules, allowing them to escape into the gas phase.
