Q1; b: an An electric kettle contains a metal heating element to heat water. b. Name the process by which heat is transferred to heat all the water.

In the water in the pot, convection currents are set up, helping to heat the water uniformly. While watching the campfire you feel the heat of the glowing fire via radiation. Heat transfer in fluids generally takes place via convection.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
