Answer:
T₂ = 19.95°C
Explanation:
From the law of conservation of energy:
where,
mc = mass of copper = 37.2 g
Cc = specific heat of copper = 0.385 J/g.°C
mw = mass of water = 188 g
Cw = specific heat of water = 4.184 J/g.°C
ΔTc = Change in temperature of copper = 99.8°C - T₂
ΔTw = Change in temperature of water = T₂ - 18.5°C
T₂ = Final Temperature at Equilibrium = ?
Therefore,
<u>T₂ = 19.95°C</u>
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important –<u> mass, and distance</u>. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Explanation:
Answer:
gasese molecules are always in free state
Homogenous mixture is a mixture of the "same" , uniform though out. Like mixing salt into water and the salt dissolves.
Heterogenous mixture is a mixture that is not uniform. Like mixing oil and water. You can see the two compounds within the mixture.
