Specific heat capacity and latent heat.

In summary, by placing a 210 heater in 2 kg of water and switching it on for 200 seconds, the temperature rise produced can be determined by using the specific heat capacity of water and relevant equation, taking into account the units of specific heat capacity and the quantities in the question.

a 210 heater is places in 2 kg of water. What temperature rise is produced if the heater is switched on for 200 seconds?

I need your help please.

You need to look up the specific heat capacity of water. Think about the units of specific heat capacity and the units of the quantities in the question. How can these all be combined to give you an answer in the correct units?

Well, it's easy to look up the specific heat capacity for water... just type it into Google or something. Then you need to think about how to use this information - again, the units will be a big hint and will tell you what the specific heat capacity represents.

Also try looking for the relevant equation. That should help you along the way to determining the answer.
 

What is specific heat capacity?

Specific heat capacity is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius.

How is specific heat capacity measured?

Specific heat capacity is measured by using the formula Q = m x c x ΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.

What factors affect the specific heat capacity of a substance?

The specific heat capacity of a substance is affected by its molecular structure, mass, and temperature. Substances with more complex molecular structures tend to have higher specific heat capacities, while substances with higher mass have lower specific heat capacities. Additionally, the specific heat capacity of a substance changes with temperature, with most substances having a higher specific heat capacity at lower temperatures.

What is latent heat?

Latent heat is the amount of energy required to change the state of a substance from one phase to another, such as from solid to liquid or liquid to gas, without a change in temperature.

How is latent heat different from specific heat capacity?

Specific heat capacity and latent heat are both measures of a substance's ability to store and release heat energy. However, specific heat capacity refers to the amount of energy required to change the temperature of a substance, while latent heat refers to the amount of energy required to cause a change in state. In other words, specific heat capacity deals with temperature changes, while latent heat deals with phase changes.
