Q1. There exist plants that can regulate their internal temperature by altering the rate at which they produce energy. When such plants get covered by snow, they can increase the production of energy so that their thermal radiation melts the snow in order to reexpose them to sunlight. We assume that the internal temperature for one of such plants is 22C. We make an assumption that we can model this plant as having cylindrical shape that has a height of 5.0 cm and a radius of 1.5 cm. We assume that this cylinder is surrounded by a snow wall at temperature Tam : 3.UC. (a) Draw a diagram of this plant surrounded by the snow wall. (b) What is the surface area of this plant when it is modelled as a cylinder? This will be the area exposed to the snow. (c) What is the rate of the energy loss of this surface area to thermal radiation if the emissivity is 0.80 {in a steady-state situation)? (d) What is the rate of the gain of energy by thermal radiation from the plant's environment? (e) What is the net rate of energy exchange via thermal radiation between plant's curved side and the snow
