How much thermal energy must be removed from a 0.34-kg chunk of ice to lower its temperature by 6.0 ∘C? HELP
To find the amount of thermal energy that needs to be removed from the ice, you can use the equation:
Q = m * c * ΔT
Where:
Q represents the thermal energy
m represents the mass of the ice chunk (0.34 kg)
c represents the specific heat capacity of ice (2.09 J/g⋅ºC or 2090 J/kg⋅ºC)
ΔT represents the change in temperature (-6.0 ºC)
Let's plug in the values and calculate:
Q = 0.34 kg * 2090 J/kg⋅ºC * -6.0 ºC
Q ≈ -4391.2 J
Therefore, you would need to remove approximately 4391.2 Joules (J) of thermal energy from the ice chunk to lower its temperature by 6.0 ºC.
