If the distances are all equal, then it's all a matter of the product
of the two masses. So we have to find the pair with the greatest
product of their masses.
It seems like that would be a person and the Earth. ( B. )
Answer: a compound is a substance that is made up of more than one type of atoms bonded together, mixtures are a mix of multiple elements or compounds which haven't bonded together.
Explanation:
Consider a hypothetical reaction:
A ↔ B
The change in free energy, ΔG can be related to the equilibrium constant K as:
ΔG = -RT ln K
i.e. K = exp (-ΔG/RT)
When ΔG is negative, the exponential becomes positive which results in a high value of the equilibrium constant (K). More and more of the reactants get converted into products and the reaction tends to be spontaneous.
Answer:
The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules
Explanation:
As we know
Amount of heat gained
Q = mc (T2-T1)
Here,
mass of water in cup 2 (m) = 79.10 grams
Temperature of water in cup 2 = 16.8 degree Celsius
Specific heat of water (c) = 4.186 J/(g °C)
Final Temperature of water in cup 2 = 23.2 degree Celsius
Substituting the given values, we get -
Q = 79.10 * 4.186 * (23.2 -16.8) = 2119.121 Joules
The amount of heat gained by the water in cup 2 after adding the hot object(s) to it is 2119.121 Joules
