note: that is not the electronic configuration, that is the Bohr model.
I don't know about 14, but 15 is (4), because a liquid draws in heat to turn into a gas. 16 is (2), because to turn into a cold solid, something has to release heat.
Wood sinks in ethanol => wood has higher density than ethanol.
wood floats in gasoline=> wood has lower density than gasoline
Answer:
a) A satellite is warmed by sunlight.
Explanation:
Heat transfer by radiation mostly involves heat gain or heat loss from the Sun. In this case, Option A is the only option where sunlight is involved so it is the best example of heat transfer by radiation.
2. B because it has a lower activation energy.
idk because you have no picture with the lines on it
