Plan an investigation using solid and liquid water to show that thermal energy is not the same as temperature.
algol [13]

The investigation using solid and liquid water to show that thermal energy is not the same as temperature is:

  • Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

<h3>What is the response to the experiment above?</h3>

The response is No, because the lake is known to have a lot more particles than the glass of water and so they will not have the same  thermal energy.

Note that the temperature is seen as the an average and thermal energy is seen to be the total. A glass of water can be able to have the same temperature as what we call Lake Superior, but the lake has a lot of thermal energy due to the fact that the lake has a lot of water molecules.

So the investigation using solid and liquid water to show that thermal energy is not the same as temperature is Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

In the unbalanced equation given below, what is the element that is gaining electrons?
viktelen [127]

Hey there!:

HCl + MnO2 → MnCl2 + H2O + Cl2

* in HCl the oxidation state of Cl is -1 .

* on the product side the oxidation state is 0 .

* therefore Cl gains electrons .

* in  MnO2 the oxidation state of Mn is +4

* in MnCl2 the oxidation state of Mn is +2

Therefore Mn loses electrons

Answer A

Hope That helps!
