What happens when we apply pressure to the particles of matter?Īns: Pressure can be defined as the force applied per cross-sectional area.
What is evaporation? What are the factors affecting it?Īns: Evaporation can be defined as the process of conversion of a substance from its liquid state to a gaseous state at any temperature below its boiling point.Įvaporation will be dependant on the factor below:ġ6. What produces more severe burns, boiling water or steam?Īns: When the steam gets converted into boiling water it releases latent heat of water which results more severe burns when we compare it to boiling water.ġ5. Therefore ice at 273 K is more effective in cooling than water at the same temperature.ġ4. Why is ice at 273 K more effective in cooling than water at the same temperature?Īns: Ice will be producing a more intense cooling effect as compared to water at 273 K because at 273 K ice will be absorbing latent heat of melting from the surroundings and will be getting converted into water. Since room temperature always lies between 0 ⁰C and 100 ⁰C and within this range the physical state of water is liquid so water is liquid at room temperature.ī) An iron almirah is a solid at room temperature.Īns: Since the room temperature is very less than the melting point of iron hence an almirah made up of iron will be a solid at room temperature.ġ3. Oxygen100 ⁰C water is in a gaseous state. Arrange the following substances in increasing order of forces of attraction between the particles- water, sugar, and oxygen.Īns: The order of increasing forces of attraction between the particles is as follows:
Suggest a method to liquefy atmospheric gases.Īns: One method to liquefy atmospheric gases is to decrease the temperature and increase the pressure.Ħ. For any substance, why does the temperature remain constant during the change of state?Īns: The reason behind the temperature of substance or matter remaining constant during a change of state is that during the change of state all of the heat or energy provided to particles of matter is utilized to take the particles of matter apart from each other.ĥ. What is the physical state of water at:Īns: The boiling point of water is 100 ⁰C, hence the physical state of water at 250⁰C will be gaseous.Īns: The boiling point of water is 100 ⁰C, hence at 100 ⁰C water is in the gaseous state.Ĥ. Convert the following temperature to a Celsius scale:ģ.
