Due to the tilt of the earth
Answer:
Iron + copper(II) sulphate → iron sulphate + copper
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
copper + silver nitrate → copper nitrate + silver
Cu (s) + 2AgNO3 (aq) → Cu(NO3)2 (aq) + 2Ag (s)
1.
Solids hold their shape and have a fixed volume. The molecules in solids are packed closely together and cannot be moved. Solids also have slow diffusion and low vapor pressure.
2.If an amorphous solid is maintained at a temperature just below its melting point for long periods of time, the component molecules, atoms, or ions can gradually rearrange into a more highly ordered crystalline form
3.A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume
Answer: The new temperature is 
.
Explanation:
Given: 
= 1.90 L, 
= 5.70 L, 
Formula used to calculate new temperature is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the new temperature is .
<span>The liquid form of matter is usually more dense than its gas form. This is because liquid molecules are closer together compared to gas molecules. An exception, however, is water. Water's solid form or ice is less dense than its liquid form because of the orientation of hydrogen bonds that lowers its density.</span>
