Answer:

Explanation:
Hello,
In this case, as the copper's heat loss is gained by the water, the following energetic relationship is:

Therefore the equilibrium temperature shows up as:

Thus, by knowing that water's heat capacity is 4.18J/g°C, one obtains:

Best regards.
The answers are low concentrated (dilute) and high concentrated respectively.
As the low concentrated salt solution has a higher water potential than that of the high concentrated salt solution, water molecules will flow from the region of higher water potential to the region of lower water potential, thus from the dilute salt solution to the high concentrated salt solution. This is due to the movement called osmosis. Note that osmosis also requires water to flow through a differentially permeable membrane, which means the membrane can allow certain substances (not all) to go in or out. If the differentially permeable membrane is not present, the movement of water molecules may be regarded as diffusion.
Therefore, the answers for the blanks are low concentrated and high concentrated.
Rdaioactive decay results in the formation of a different element. Plutonium decays by emitting alpha emission to form uranium. Thermal energy is emitted as the alpha particles are absorbed and the kinetic energy is converted to heat. The amount of energy is computed by the formula;
E = mc²
E = 0.000046 × (3 ×10^8)
Energy = 4.14 ×10^13 Joules
Answer:
if the density is higher than water than the object will sink
