Q

How would you find the volume of a marble in the laboratory using a GRADUATED CYLINDER?:

A
  1. Put some water into a graduated cylinder and note down what the volume of water is
  2. Place the marble into the graduated cylinder and record the graduated cylinder increase in the volume of the water
  3. Subtract the two numbers to find the volume of the marble

Q

SOLID
- Very little kinetic energy

LIQUID
- Increasing amount of kinetic energy

GAS
- Highest amount of kinetic energy

Study These Flashcards
A

Movement of Kinetic Energy

22
Q

SOLID
- Highly organized

LIQUID
- Less organized than solid state, but more organized than gas

GAS
- No organizational structure

Study These Flashcards
A

Structured Organization

23
Q

What happens to the properties of substances when they are combined into new compounds?:

Study These Flashcards
A
  • The properties of substances change when they are combined to form a compound
    EX: Oxygen and Hydrogen gas forming water
24
Q

What happens to the properties of substances when they are mixed together?:

Study These Flashcards
A
  • The properties DO NOT change when they are mixed together
25
Define Energy:
- The ability to do work
26
What are you actually measuring when you use a thermometer to measure temperature?:
- You are measuring the AVERAGE KINETIC ENERGY OF A SUBSTANCE
27
What is Exothermic Change?:
- Energy being released to the EXTERNAL environment/surroundings (Flowing OUT of the system) EX: Candle Flame/Fire (RELEASING energy)
28
What is Endothermic Change?:
- Energy being ABSORBED from the environment/surroundings (Flowing INTO the system) EX: Cooking an egg (ABSORBING energy)
29
Define the Law of Conservation of Energy
- Energy cannot be created of destroyed
30
If you placed a piece of ice in a mug of steaming hot water, describe the energy changes that will occur:
- Heat energy from the hot water is transferred to the ice, the energy transfer will stop once EQUILIBRIUM is reached.
31
What is the underlying heat flow concepts of Calorimetry?:
- The energy RELEASED by the system is ABSORBED by the surroundings
32
Define Heat:
- The **total amount of kinetic energy in a substance** that is transferred from a hot to cold object ~ *Heat is depending on the temperature and the mass of a substance*
33
Define Temperature:
- Temperature is the average kinetic energy in a substance
34
What is specific heat capacity?:
- Specific heat capacity is the amount of energy required to raise the temperature of one gram of substance by one degree Celsius The LOWER heat capacity, the GREATER temperature The GREATEST heat capacity, the LOWER temperature
35
What will heat up more with the same amount of energy: sand or water? Which has the higher specific heat capacity?:
- Water has HIGHER heat capacity, it will heat up SLOWER - Sand has LOWER heat capacity, it will heat up QUICKER
36
What is thermal equilibrium?:
- Thermal equilibrium is reached when the heat transfer from the hotter to the colder substance stops and when both substances are at the SAME temperature
37
Giga's prefix
- G *LARGEST METRIC AMOUNT*
37
Mega's prefix:
- M
38
Kilo's prefix:
- K or k
