If heat energy is removed from an object, its temperature will...?

Question

A. Fall
B. Fall then rise
C. Stay same
D. Rise

Answer 1

If heat energy is removed from an object, it would fall. For people who says B, it is wrong, since although in real life, when you ice a higher temperature object, it's temperature would rise again, it isn't in this problem since the question asks if we remove energy from it, and never state that we'd add energy to it again.

Answer 2

Say an object is at some T at time 1. This object has a mass, m, and a spefic heat capacity, Cp.

If you remove heat, Q, from teh object, the governing equation dictates the temperatue would fall.

Q = mCp* delta T = m Cp* (T2-T1). Since we're removing heat, Q is a negative term. Thus delta T must be negative and this implies T2 < T1.

Answer 3

The answer is B, the temperature will normally fall then rise.

Answer 4

A or B depends on the method used to extract heat.

To clarify. Place a can of beer in a bucket of ice....A. But after a while the ice has melted and it will warm up to room temperature again.... B.

Answer 5

A. Fall

Answer 6

warmth is a sort of skill. each and every substance (remember), includes Atoms and/or Molecules. At any temperature above Absolute 0 (-273.15°C), those are in consistent action thereby possessing 'Kinetic skill. They consequently incorporate 'warmth skill' even while incredibly chilly. 'chilly' won't be in a position to be added to or transferred from a substance.. warmth can purely pass from warm to chilly components. Coldness is relative to a distinctive substance having a some distance better temperature from which warmth will pass in one direction purely...in direction of the chillier substance. once you place your hand in chilly water, the sensation of 'Coldness' is using the warmth being transferred into the chilly water, the nerves deliver messages to the concepts which tells you the water is chilly relative to the hotter hand. As 'clever' warmth skill is added to a substance, the molecules develop into greater excited and their action, (Kinetic skill), will develop ensuing in a upward thrust in temperature which could be measured via a thermometer or 'Sensed', (felt) via the hand. while Ice below 0°C is heated this is temperature will develop (develop into warmer) and, while water at 0°C is heated this is going to develop into warmer (bigger temperature). At 0°C, the ice will start to soften as greater warmth is added. The temperature at this factor won't develop added. It continues to be at 0°C until eventually all the ice has melted to water at 0°C. the warmth being added is getting used to develop the Kinetic skill of the molecules to the factor of moving aside and beginning to bypass (Melting). Water, being heated from 0°C to a hundred°C, is increasing Kinetic skill and consequently temperature is increasing (Addition of clever warmth lower back). At a hundred°C, The addition of greater 'Latent warmth' (of vaporisation) strikes molecules added aside as their Kinetic skill will develop until eventually they could wreck aside and variety Steam at a hundred°C...lower back, NO substitute in Temperature until eventually all the water is vaporised....The steam can then be 'Superheated' to any temperature.
