Answer:
The pennies are NOT made of pure copper since the obtained density is 9.29 g/cm3 which is greater than the density of copper which is 8.96 g/cm3.
Explanation:
Ch4 is the lowest boiling point
Correction: The temperature change is from 20 °C to 30 °C.
Answer:
Cp = 1.0032 J.g⁻¹.°C⁻¹
Solution:
The equation used for this problem is as follow,
Q = m Cp ΔT ----- (1)
Where;
Q = Heat = 5016 J
m = mass = 500 g
Cp = Specific Heat Capacity = ??
ΔT = Change in Temperature = 30 °C - 20 °C = 10 °C
Solving eq. 1 for Cp,
Cp = Q / m ΔT
Putting values,
Cp = 5016 J / (500 g × 10 °C)
Cp = 1.0032 J.g⁻¹.°C⁻¹

<h3><u>Explanation; </u></h3>
- Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
- Nuclear reactions are used to release nuclear energy that generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.
- Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
- Nuclear energy may be used in a wide variety of fields as it generates high levels of electricity without causing damage to our environment and atmosphere.
