Suppose a bag full of ice 450g
WebOct 4, 2024 · Answer: The final temperature of water is 54.5 °C. Explanation: Given data: Energy transferred = 65 Kj Mass of water = 450 g Initial temperature = T1 = 20 °C Final temperature= T2 = ? Solution: First of all we will convert the heat in Kj to joule. 1 Kj = 1000 j 65× 1000 = 65000 j specific heat of water is 4.186 J /g. °C Formula: q = m × c × ΔT WebSuppose a bag full of ice (450 g) at 0.0 °C sits on the counter and begins to melt to liquid water.
