Specific heat of hot water Solution

Follow our step by step solution on how to calculate Specific heat of hot water?

FIRST Step Consider the formula

ch = (ϵ \cdot \frac{C min}{mh}) \cdot (\frac{1}{\frac{T1 - t2}{T1 - t1}})

Next Step Substitute values of Variables

∴

ch = (8 \cdot \frac{30}{285kg/s}) \cdot (\frac{1}{\frac{60K - 25K}{60K - 10K}})

Next Step Prepare to Evaluate

∴

ch = (8 \cdot \frac{30}{285}) \cdot (\frac{1}{\frac{60 - 25}{60 - 10}})

Next Step Evaluate

∴

ch = 1.20300751879699J/(kg*K)

LAST Step Rounding Answer

∴

ch = 1.203J/(kg*K)
