Question 1
A laboratory experiment shows that 500g of iron at 120Β°C is placed into 600g of water at 25Β°C. Calculate the final temperature if the specific heat of iron is 0.45 J/gΒ°C. Assume no heat loss to the surroundings.
π‘ Hint: Remember to keep track of the energy transferred from iron to water.
Question 2
Consider a system where 250g of a substance (specific heat = 3.0 J/gΒ°C) loses 1000 J of heat. What is the temperature change? Use Q = mcΞT.
π‘ Hint: Make sure to plug in the values correctly and pay attention to the units.
