SG Week 7 Review/Reflection

Heat Capacity(C)

Amount of heat energy needed to rise the temperature of the WHOLE or SYSTEM by one degree/ Kelvin

Heat Cap = Heat / (Change in temperature)

Specific Heat Capacity (c)

• Amount of heat energy required to raise the temperature of a unit of mass of substance/something by ONE degree/Kelvin
  
  Specific heat = Heat/ (mass) * (change in temperature)

Endothermic Process

Taking in heat

Exothermic Process

Losing energy

Potential Energy

Stored Energy

or

Chemical Bonds

Kinetic Energy

When things are in motion

or

Motion of Particles

System

Part of the thing that being studied

Surrounding

Everything else thats NOT being studied

Heat (q)

Energy transfers when there is a difference in temperature.

Work(w)

Work = Force * Distance

Signs of Heat(q) and Work(w)

Q + W = Change in Energy

Enthalpy(H)

Heat energy thats is with the chemical reaction.

Kinetic Molecular Theory

Gas at atomic level

Kinetic Molecular Theory: Assumptions 1

Particle Volume: Gas particles are super super tiny. They take up almost no space.

Kinetic Molecular Theory: Assumptions 2

Particle Motion: They are always randomly moving in all directions. Move unless they collide with wall or other particles

Kinetic Molecular Theory: Assumptions 3

Nothing attracting gas particles; Gas don’t attract each others so they are stay single for fever sadly.

Effusion

Process where a gas escapes through a tiny hole

Diffusion

Direction of a gas through another gas.
