What were Lamarck's ideas about evolution and Why were those ideas incorrect?
<em><u>→</u></em><em><u> </u></em><em><u>These and other examples show that Lamarck's theory does not explain how life formed and became the way it is. The other way that Lamarck's theory has been proven wrong is the study of genetics. Darwin knew that traits are passed on, but he never understood how they are passed on.</u></em>

The heat energy required to raise the temperature of 1500 g of aluminium pot by 100°C is 135 kJ.
The heat energy required to raise the temperature of 1500 g of copper pot by 100 °C is 57.75 kJ.
Explanation:
The heat energy required to raise the temperature of any body can be obtained from the specific heat formula. As this formula states that the heat energy required to raise the temperature of the body is directly proportional to the product of mass of the body, specific heat capacity of the material and temperature change experienced by the material.
So in this problem, the mass of the aluminium is given as m = 1500 g, the specific heat of the aluminium is 0.900 J/g °C. Then as it is stated that the temperature is raised by 100 °C, so the pots are heat to increase by 100 °C from its initial temperature. This means the difference in temperature will be 100°C (ΔT = 100°C).
Then, the heat energy required to raise the temperature will be
Thus, the heat energy required to raise the temperature of 1500 g of aluminium pot by 100 °C is 135 kJ.
Similarly, the mass of copper pot is given as 1500 g, the specific heat capacity of copper is 0.385 and the difference in temperature is 100 °C.
Then, the heat energy required to raise its temperature will be
And the heat energy required to raise the temperature of 1500 g of copper pot by 100°C is 57.75 kJ.
So, the heat energy required to raise the temperature of 1500 g of aluminium pot by 100°C is 135 kJ. And the heat energy required to raise the temperature of 1500 g of copper pot by 100 °C is 57.75 kJ.
