The lower the airflow over the surface, this keeps the concentration of the condensing gas as high as possible. Considering the internal and external pressures of a container of gas. Specific heat capacity of materials. For more gas calculation see P-V-T pressure-volume-temperature gas laws and calculations. Pressure in fluids. How is Specific Heat Capacity Determined? From measurements of volumes and pressure of gases at constant pressure, a numerical inverse law can be formulated.

The following diagram shows the formula for specific latent heat. Scroll down the.
Examples of simple gas calculations. If the cylinder and its contents increase in temperaturethen the thermal energy store is increased as the gas particles gain kinetic energy.
Foreign Language. Examples of endothermic and exothermic processes and shown as are methods for determining the heat capacity of a metal. State cha. To convert from one to the other, the following simple formulae apply.

|A simple experiment to illustrate a 'heating curve'. Increasing the energy store of gas by compressing it. Examples of endothermic and exothermic processes and shown as are methods for determining the heat capacity of a metal.
From measurements of volumes and pressure of gases at constant pressure, a numerical inverse law can be formulated. Pressure in fluids. The greater the airflow over the surface of the faster the evaporation rate - the air can become saturated with the vapour of the liquid, so it is more readily replaced if the already evaporated liquid is swept away by air flowing over the surface.
1. Figure 1 shows three collections of molecules. One is a solid one a liquid and one a gas. Which is which?
2. Revise what latent heat is and how it relates to the changes in state, energy and mass of different materials as part of National 5 Physics. thermal energy for a change in state is measured in joules (J); mass is measured in kilograms (kg); specific latent heat is measured in joules per kilogram (J/kg).
A historical curiosity - latent heat 'hidden' heatwhich was unexplained until the particle theory of matter was developed.
The greater the surface area, the faster the evaporation - more area, more chance of evaporation. More on methods of reducing heat transfer eg in a house and investigating insulating properties of materials.

Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials. You Selected: Keyword specific heat capacity.
Help with GCSE Physics, AQA syllabus A AS Level and A2 Level physics. It is written and Specific Heat Capacity and Latent Heat Questions - GCSE standard. 1) How much heat is needed to transform g of ice at oC into water at 50 o C? (cice = cwater / 2). Table of latent heats here. 2) a) 4 kg of water (at 25 oC).
If the temperature is kept constant and the volume increased, the impacts are more spread out and less frequent per unit area, so the gas pressure decreases.
In fact, the average kinetic energy of the gas particles is directly related to the temperature. Remove the boiling tube and record the temperature of the melted acid. So, the lowest possible temperature that is possible is o C.
Students will be able to explain and calculate specific heat capacity.

Calculations involving specific heat, heat capcity and latent heat problems and exercises
Conversely, if a gas is compressed into a smaller volume at constant temperature, the number of impacts per unit area increases, so the pressure increases. The internal and external pressures are not balanced, but that's no problem with a strong steel walled cylinder! Pressure in fluids.
