How is convection used in tornadoes

so i tried so hard to find an answer but most of my google is blocked sooo : )

This drawing shows a human body system. what is the primary function of this body system?

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate, m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

8) warming your hands by a fire is an example if which heat transfer? a. conduction b. convection c. radiation d. none of these
