Heat gained by metal = heat lost by water.rrosa522 said:Homework Statement
When 1.25 kg of a cold metal at a temperature
of 263 K was immersed in 1.43 kg of water at
a temperature of 365 K, the final temperature
was 336 K. What is the specific heat capacity
of the metal?

And there are a couple of typos as well, it should be written as 1.90 kJ/(kgK)CWatters said:That's not an attempt at a solution.
Specific heat capacity, also known as specific heat, is the amount of heat energy required to raise the temperature of one unit of a substance by one degree Celsius. It is a measure of how much heat a substance can hold and how quickly it can absorb or release heat.
To calculate specific heat capacity, you divide the amount of heat energy transferred to a substance by the change in temperature and the mass of the substance. The formula is Q = mcΔT, where Q is heat energy, m is mass, c is specific heat capacity, and ΔT is the change in temperature.
The units for specific heat capacity are joules per kilogram per degree Celsius (J/kg·°C) in the SI system and calories per gram per degree Celsius (cal/g·°C) in the metric system.
Specific heat capacity varies between substances because it depends on the chemical makeup and structure of the substance. For example, water has a higher specific heat capacity than most other substances, meaning it can hold more heat energy and takes longer to heat up or cool down.
Specific heat capacity is important in science because it helps us understand how different substances react to heat energy. It also plays a role in many everyday processes, such as cooking and weather patterns. Additionally, specific heat capacity is used in thermodynamics and other fields of science to study the properties of materials.
