- Homework Statement
- A 150g steel spoon (constant = 420J/kg degrees Celsius) initially at 19 degrees Celsius is placed into a 250mL cup of water at 89 degrees Celsius. When both objects reach the same temperature what temperature will that be?

- Relevant Equations
- change in energy = (mass)(constant)(change in temperature)

water constant = 4200J (kg degrees Celsius)

I don't know what to do!
