Increase in thermal power makes a liquid particles to relocate quickly and also eventually the fluid transforms right into vapour or steam which has high amounts of heat energy. However, as the liquid steam cools, the thermal energy is lost,and the fluid progresses to freezing right into ice,which is merely liquid without thermal energy.
You are watching: Which of these indicates that a liquid has transferred thermal energy to the air?
The liquid decreases in temperature and also its particles shed KE.Temperature is proportional come KE, for this reason if temp. Decreases, KE decreases.Energy has actually been removed from the liquid, since it is currently "in the air".
For troubles 1-3, take into consideration a simple dc brush motor with a permanent magnet stator. With an an consider a basic dc brush motor through a permanent magnet ae it is provided voltage that 100 v, the no-load rate of the engine is 1000 rpm. This engine can carry out a talk of 1.9 n-m in ~ 800 rpm drawing a present of 2 a existing are both zero in ~ no load.) 1. Through an armature it is provided voltage of 100 v, the motor is activate at 900 rpm. What is the engine torque? what is the mechanically power delivered by the motor? what is the existing draw? what is the electrical power input? what is the energy efficiency of the motor? through an armature it is provided voltage of 100 v, the engine is activate at 1100 rpm (where that acts together a generator). What torque input is required? what mechanical strength is required what existing is generated? what is the electrical power generated? what is the energy efficiency of the motor acting as a generator? 2. V an armature supply voltage elevated to 120 v, the engine is operated at 1000 rpm. What is the no-load speed? what is the motor torque? what is the mechanically power delivered by the motor? what is the current draw? what is the electric power entry what is the energy performance of the motor? 3.

We have a colorless transparent liquid. It looks favor water. We seperated it right into a solid and also a fluid by evaporration and also condention to be this a chemichal or a physical seperation a. Chemical seperation b. Physics seperation
