A liquid with a specific heat capacity of 4.18 J/g·°C is required to increase its temperature from 20 °C to 80 °C with an intake of 1,500 J. What is the mass of the liquid?
💡 Hint: Rearrange the formula to solve for mass.
If 250g of ice at -10°C absorbs 25,000 J of heat before melting, calculate how much more heat it requires to raise the temperature of the resulting water from 0°C to 100°C. (c for water= 4.18 J/g·°C)
💡 Hint: Consider both melting and heating separately.
