1. we see water droplets collected on the outer surface of a glass container, containing ice because of heat transformation from hot body to cold body . when we put ice in a glass container temperature of ice is less than the temperature of atmosphere that's why there is a flow of energy is started between hot body to cold body (glass container containing ice and atmosphere) so ice started melting and tiny water droplets are shows on outside of the container.
2. Solids have fixed shape but liquids and gases do not have fixed shape this can be explained on the basis of their molecular arrangement ,
In case of solids - in solids there is very strong force of attraction between the particles of solids hence there is negligible space between them that's why they are bounded very strongly to move freely. . this is the reason they have fixed shape .
in the case of liquids and gases - In liquids there is weak force of attraction between the particles of liquids and they are bounded with each other with weak strong forces and continuously do motion in the container in a zigzag way. while in gases there id very low force of attraction between then particles and hence they are distributed freely inside the container this is also a reason they have maximum kinetic energy comparison to liquids.
3. Why is it advisable to use pressure cooker at higher altitudes , because of low pressure . At high altitude pressure is low in comparison to other areas . as we know that boiling point is directly proportional to the pressure so its takes lots of time to boil water use of pressure cooker maintained pressure so water boils easily and cooked easily.
4. fluids are the substances which can flow , liquids as well as gases.
5. At 25 degree centigrade( mostly room temperature) it is into liquid state because of weak bonds between hydrogen and oxygen.
