Explanation:
Heat transfer by convection involves gases and liquids as a result of density differences when they are heated.
In the hot air balloon, the air closer to the heater is warmed. This air becomes lighter and it rises. This in turn pushes the balloon up. The cold air away from the heater is denser and begins to sink.
This exchange of hot and cold air sets up convection cells within the balloon and this how heat transfer is attained.
Hello. You did not present the measurements of the triangular prism, which makes it impossible for the surface area of this prism to be calculated. However, I will try to help you in the best possible way.
To calculate the surface area of the triangular prism, you will first need to identify the value of the side surface and the value of the base area. The value of the lateral surface corresponds to the area of the three rectangular sides of the figure.
After these values are identified, you must multiply the value of the base area by 2 and add the result to the value of the side surface. The result corresponds to the surface area of the rectangular prism. This can be represented by the formula:
surface area = lateral surface + (2 * base area)

False....I believe at least its false<span />
