- A thermodynamical system performs work and at the time exchanges energy to the outside environment ther is more additional help or changes in terms of fuel supply or an increase in the temp of the system the work done by the system on the environment is 1.5 x 10^ 6 while the systems internal energy is increased by 5.5 x 10^ 6 J how much heat is exchanged between the system and the environment? Pls indicate the direction of the heat flow?Over the course of a day, 4.0 kg of water evaporates from the leaves of a corn plant. a) How much energy is required to evaporate the water? (Assume that the temperature of the leaves is 30C.) b) If the plant is active for 12 hours, how much power does this correspond to? You can think of this as the necessary power to drive transport in the plant.800 J of work are done BY a system in a process that decreases the thermal energy of the system by 50 J. How much heat is transferred TO the system during this process? If the system gains heat, answer with a positive number. If the system loses heat, answer with a negative number. (in J) -750 750 -850 -50 0
- An electric power plant uses energy from burning coal to generate steam at 450oC. The plant is cooled by 20oC water from a nearby river. If burning coal provides 100MJ of heat, what is the theoretical minimum amount of heat that must be transferred to the river during the conversion of heat to electric energy? a- 100MJ B- 90MJ c- 60MJ D- 40MJFrom the perspective of energy efficiency an ideal cooking utensil should not absorb a large part of the thermal energy it receives from the stove. It also should not change its size as it is heated. In terms of the specific heat S and coefficient of thermal expansion a, which choice below satisfies these requirements? Both S and a should be large. Both S and a should have small values. Small S but large a. Large S but small a.Copy of A heat engine is used to convert heat into work.
