Explanation

The pressure of a gas in a container is affected by:

• Temperature (increases with temperature)
• Volume (decreases with increasing volume)
• Density of gas (increases with density)

However, the material of the container does not directly affect the pressure of the gas.

Explanation

• During the daytime, plants require Carbon Dioxide (CO2) for photosynthesis.
• Which is the process by which they produce glucose and oxygen.

Explanation

• Distillation is a process that involves boiling the seawater and then collecting the condensed steam, which is free from salt and other impurities, resulting in fresh drinking water.
• This process is commonly used in desalination plants to produce drinking water from seawater.

Explanation

Marasmus is a form of severe protein-energy malnutrition, characterized by a lack of sufficient protein and calories in the diet.

It is most commonly seen in children under the age of 5, particularly in developing countries where access to nutritious food is limited.

Marasmus is caused by a severe deficiency of protein and calories, leading to:

• Wasting of muscles and tissues
• Weight loss
• Fatigue
• Weakness
• Poor growth and development

Explanation

• Herbivores are animals that eat only plants, including leaves, stems, roots, flowers, fruits, and seeds.
• Examples of herbivores include cows, deer, rabbits, and elephants.

Explanation

• Dust and gas in the interstellar medium (ISM) can absorb and scatter starlight.
• It leading to a reduction in the brightness of stars as seen from Earth.
• This is known as interstellar extinction.

Explanation

• Thermometer is the instrument used to measure temperature.
• It is a device that measures the temperature of a substance or environment, typically consisting of a glass tube filled with a liquid that expands or contracts in response to changes in temperature.

Explanation

• Sublimation is the transition of a substance from the solid to the gas phase without going through the liquid phase.
• Glucose and Sodium Chloride do not sublime, as they require a liquid phase transition before turning into a gas.

Here are the some solid sublime material:

• Iodine
• Camphor or Dry ice

Explanation

• Carbon Dioxide (CO2) is a greenhouse gas that traps heat in the Earth's atmosphere.
• It contributing to the greenhouse effect and global warming.

Explanation

• Crystallization is the process of separating a soluble solid from a solution by allowing the solution to cool and form crystals.
• This process is used to purify substances and obtain a solid in a pure form.
