If the two objects are placed in contact, will they experience the same temperature change?

Question

Two objects are made from the same material. They have different masses and temperatures.

If they don't experience the same temperature change, which object will experience the greater temperature change?

Please provide sources of info...I don't want faulty information.

Answer 1

The relationship between heat flow Q, mass m, specific heat c, and temperature change ΔT is

Q = m C ΔT

The two objects placed in contact WILL experience the same heat flow; whatever one gains, the other will lose. However, if they have different masses, they will experience different temperature changes. One teaspoon of boiling-hot water dropped into a cup of ice-cold water does not raise the temperature of the aggregate to 50 degrees C!

You don't need sources. You just need to observe the world around you to know the right answer (without a book!). You can see this for yourself, and you'll learn more than if someone just gives you the answer. You don't even need a thermometer, but you can use one if it helps.

Make a thermos full of boiling hot water, or even just a large coffee mug. Break an ice cube into small pieces and drop one piece in. These are your two objects of identical material and different masses. The sliver of ice is small (has little mass) compared to the amount of water in the thermos (has greater mass). What happens to the ice? Does the hot water experience much of a temperature change? What about the ice?

Start with fresh boiling water and drop in a whole ice cube. Does this change the temperature of the water more?

Try again with a handful of ice.

Given these observations, what kind of prediction could you make about any two objects as described?

Answer 3

you don't need aspects. you basically want to note the international round you to carry close the finest answer (and not in any respect utilizing a handbook!). you'll discover this for your self, and also you would learn better than if someone basically promises the answer. you do not even want a thermometer, yet you should use one if it facilitates. Make a thermos packed with boiling sizzling water, or maybe only a good espresso mug. wreck an ice dice into small parts and drop one piece in. those are your 2 products of equivalent fabrics and magnificent lots. The sliver of ice is small (has little mass) compared to the quantity of water interior the thermos (has better mass). What takes position to the ice? Does the nice and cozy water adventure an excellent style of a temperature replace? What about the ice? commence with sparkling boiling water and drop in a finished ice dice. Does this transformation the temperature of the water better? attempt back with a handful of ice. Given those observations, what style of prediction might want to you're making about any 2 products as defined?

Answer 4

Based on the second law of thermodynamics, heat always flow from a higher temperature body to a body of lesser temperature. Therefore the hotter body will become colder while the colder body will become hotter. Also, a body with a higher mass can absorb or release more energy.

They will not experience temperature change only if their temperatures are equal.

Answer 5

If you dont want faulty information check yourself, try google or ask. You run the risk of getting opinions when you post here. If the objects have different mass and temperatures it seems rather obvious that the smaller object will be warm and cold faster.

Answer 6

When they are placed in contact, the temperature will become equal. If they are made from the same material, it simply means that specific heat is same. But even if they are of different materials and the specific heats are thus different, the logic remains same.

Heat flow is similar to flow of a liquid from a higher level to a lower level.

Answer 7

heat transfers from high temperature object to low temperature object. the variation of temperature at two object is not equal . it do not deponds on mass and initonal temperature. they don't experience the same temperature change because they have different heat capicity.
