Weeks = 6 x 4 = 24
Mass leak rate of freon = 41.60 g/week
Mass leak rate of fluorine
Fluorine mass in Freon
= —————————————- X leak rate
M.M. Of Freon
19 x 3
——— X 41.60 = 20.010 gm/week
118.5
Total leaked in 6 months
= 24 x 20.010 = 480.24 gm = 0.480 Kg
Option d: copper.
Because copper is an element, not a mixture.
Answer:
Firsthand association assigns energy throughout conduction. Radiation transpires when particles consume energy that progresses as a wave. The heat will run from the h2O to the ice continuously until the ice has absolutely melted so both elements have reached the same temperature.
