Mattel Toys Interview Questions and Answers

Oil & gas is highly inflammable due to its low flash point and high volatility.

• Oil & gas have low flash points, which means they can ignite at relatively low temperatures.

• Oil & gas are highly volatile, meaning they evaporate quickly and form flammable vapors.

• The presence of hydrocarbons in oil & gas makes them highly combustible.

• Oil & gas can easily mix with air to form explosive mixtures.

• The high energy content in oil...read more

Low pressure and low voltage are used in petrochemical plants for safety and efficiency reasons.

• Low pressure is used to prevent leaks and accidents in the handling of volatile substances like oil and gas.

• Low voltage current is used to minimize the risk of electrical hazards and ensure worker safety.

• Low pressure and low voltage systems are more energy-efficient and cost-effective in petrochemical operations.

• Examples of ...read more

Dewpoint is the temperature at which air becomes saturated with water vapor, causing condensation to form.

• Dewpoint is the temperature at which dew forms on surfaces.

• It is a measure of the amount of moisture in the air.

• Dewpoint is affected by both temperature and humidity.

• When the dewpoint is close to the actual temperature, the air is very humid.

• Dewpoint is important in weather forecasting and HVAC systems.

The temperature at which water droplets begin to condense and dew can form is called dew point.

• Dew point is the temperature at which the air becomes saturated with water vapor and condensation begins to form.

• It varies depending on the amount of moisture in the air.

• Dew point is an important factor in weather forecasting and can affect outdoor activities such as camping and hiking.

• For example, if the dew point is high, i...read more
