Wet bulb temperature is the lowest temperature that can be achieved through evaporative cooling of a wet surface.

• It is measured using a thermometer with a wet wick around the bulb.

• It is used to determine relative humidity and dew point.

• It is an important parameter in HVAC systems and weather forecasting.

• Example: If the dry bulb temperature is 30°C and the wet bulb temperature is 25°C, the relative humidity is approxima

Humidity is the amount of water vapor present in the air.

• Humidity can be measured using a hygrometer.

• High humidity can make the air feel heavy and uncomfortable.

• Low humidity can cause dry skin and respiratory problems.

• Humidity affects the rate of evaporation and can impact weather patterns.

• Relative humidity is the ratio of the amount of water vapor in the air to the maximum amount the air can hold at a given temperatur

Chlorination is the process of adding chlorine to water to kill bacteria and other harmful microorganisms.

• Chlorination is commonly used in water treatment plants to ensure safe drinking water.

• Chlorine gas or sodium hypochlorite can be used for chlorination.

• The amount of chlorine added to water is measured in parts per million (ppm).

• Chlorination can also be used to disinfect swimming pools and other recreational water s...read more

Aluminium chloride is made by reacting aluminium with chlorine gas.

• Aluminium is first heated to a high temperature to remove any oxide layer.

• Chlorine gas is then passed over the heated aluminium.

• The reaction produces aluminium chloride as a white powder.

• The equation for the reaction is: 2Al + 3Cl2 -> 2AlCl3

• Aluminium chloride is commonly used as a catalyst in organic chemistry reactions.

Hydrogen is consumed in the reaction with chlorine gas to form hydrogen chloride.

• Hydrogen is removed from aluminium chloride by reacting it with chlorine gas.

• The reaction produces hydrogen chloride gas.

• Hydrogen chloride gas is a byproduct of the manufacturing process.

• Hydrogen chloride gas can be used in the production of PVC.

• The reaction is exothermic and releases heat.
