Chpt. 3 & 4 Test Review-Matter/ Solid, Liquids, Gas
Question | Answer |
---|---|
Name the 4 states of matter | solid liquid gas plasma |
What is the difference between an amorphous and a crystalline? | Amorphous: Has no rigorous structure and can change . Crystalline: Has an orderly 3_D structure. |
The relationship between pressure, temperature and volume in "Boyle's law" is....? | **The volume of gas varies with the PRESSURE** If the pressure increases, the volume decreases. If the pressure decreases, the volume increases. |
What is the relationship between pressure, temperature and volume in "Charles' law"? | **The volume of gas varies with the TEMPERATURE** If the temperature increases, then the volume also increases. If the temperature decreases, then the volume also decreases. |
The temperature of a substance, during a phase change, usually INCREASES? DECREASES? or STAYS THE SAME? Explain why this happens..... | STAYS THE SAME because the energy/heat is being used to break the bonds. |
What is the difference between a homogenous mixture and a heterogeneous mixture? | **Homogenous-you cannot see the individual parts. The entire mixture looks the same throughout. **Heterogeneous-yon can see the individual parts. The entire mixture looks different throughout. |
Which liquid would be the most viscous? OIL? HONEY? or WATER? | viscous means having a thick, sticky consistency between solid and liquid so it would be HONEY followed by oil, then water |
Packet of Kool-Aid in water Solute is ? Solvent is ? | Solute is Kool-Aid mix Solvent is the water |
Instant coffee Solute is ? Solvent is? | Solute is the instant coffee Solvent is the water |
Solvent of 2% milk + Solute of Nestles Quik = ? | Chocolate milk :-) |
What is known as the universal solvent? | Water |
What are 3 ways you can increase the solubility of a solution of a solid into a liquid? | You can MIX IT, HEAT IT, or CRUSH IT. |
How can you increase the solubility of a gas in a liquid? | By decreasing the temperature |
