Answer:
Where is the pic or sum ? How can i tell ?
Explanation:
First is homogeneous and so is the third. second is heterogeneous
Higher <span>C. higher than when the source is stationary</span>
Drying clothes is a physical change, because it is not permanent. The clothes could just be wettened again, therefore it is not a chemical change.
~Hope I helped!~
When a water vapor condenses, heat is being released from the process. This heat is called latent heat of vaporization since the phase change happens without any change in the temperature. This value is constant per mole of a substance as a function of pressure and temperature. For this problem, we are given the heat of vaporization at a certain T and P. We use this value to calculate the total heat released from the process. We calculate as follows:
Total heat released: 32.4 g ( 1 mol / 18.02 g ) (40.67 kJ / mol) = 73.12 kJ
Therefore, 73.12 kJ of heat is released from the condensation of 32.4 g of water vapor.
