Heat transfers from the water to the copper block until both reach an equilibrium temperature.
The transfer of heat in this system can be described by (4) The water gains heat and the block loses heat until both are at the same temperature that is between 10.0°C and 90.0°C.
This is because heat always flows from the object with higher temperature to the object with lower temperature. In this case, the water at 90.0°C has a higher temperature than the copper block at 10.0°C. As a result, heat will transfer from the water to the copper block, causing the water to cool down and the copper block to heat up. Eventually, both objects will reach an equilibrium temperature somewhere between 10.0°C and 90.0°C.

b. False
Answer:
Mendeleev was the first to develop the periodic table
Explanation:
Answer:
3*10⁹ + 5.3*10¹⁰ = 5.6*10¹⁰
Explanation:
The values are given as exponents:
3*10⁹ and 5.3*10¹⁰
As per the rules:
-Before adding two numbers, all exponents must be the same
-The addition takes place between the numerical portion of the numbers
- The final value is rounded off to the least places in the decimal portion of the given numbers
Therefore, the two numbers to be added are:
Rounded off the final value to 1 decimal place gives:
5.6*10¹⁰
