Answer 22

no heat transfer

Question 23

internal energy

Answer 23

Question 24

convection

Answer 24

• It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a cycle.

Question 25

isolated system

Answer 25

no heat and matter transfer

Question 26

closed system

Answer 26

allow heat transfer but no matter transfer

Question 27

cyanohydrin formation

Answer 27

Question 28

torque

Answer 28

Question 29

refraction

Answer 29

* the angle of incidence: angle between an **incoming ray (light, sound, or other wave) and the normal to the surface**-always equal to angle of reflection

Question 30

**Total Internal Reflection**

Answer 30

when a light ray traveling in a denser medium (higher refractive index, n₁) hits the boundary of a less dense medium (lower refractive index, n₂) at an angle **greater than the critical angle (θc)**, causing all the light to be reflected back into the denser medium instead of refracting

Question 31

Ideal gas law

Answer 31

*** PV=nRT** R=0.0821 L·atm/mol·K; V measured in L/m^3 T = Temperature (measured in Kelvin = °C + 273) 1 atm = 760 mmHg = 760 torr = 101.325 kPa

Question 32

Unit conversion

Answer 32

1 g/cm³ = 1000 kg/m³ 1L=1000 cm³

Question 33

Doppler equation

Answer 33

Question 34

boiling point

Answer 34

* the temperature at which a liquid’s vapor pressure equals atmospheric pressure. * high vapor pressure=easily escape=high esacaping rates from the liquid to gas-->low BP

Question 35

principal quantum number

Answer 35

* energy of a given orbital or electron cloud in which an electron cloud changes

Question 36

mirror lens equations

Answer 36

Question 37

Magnification Equation

Answer 37

Question 38

Converging lenses/mirrors

Answer 38

* Real/Inverted if beyond F, Virtual/Upright if inside F; * **"LUV IR" → Lenses: Upright = Virtual, Inverted = Real**

Question 39

Diverging lenses/mirrors

Answer 39

Always Virtual & Upright

Question 40

Archimede's principle

Answer 40

Question 41

sound traveling speed

Answer 41

* Sound travels fastest in solids, then liquids, and slowest in gases. * Solids have molecules that are tightly packed, allowing sound waves to transfer energy more efficiently.

Question 42

light traveling speed

Answer 42

* Slows down in glass than in air * Glass has a higher index of refraction than air.

Question 43

diffraction

Answer 43

Question 44

Answer 47

Question 48

Bernoulli’s Equation

Answer 48

* used for **large-scale, fast-moving flows** (e.g., blood in arteries, air over wings, water through open pipes) * faster moving fluid-->less pressure

Question 49

Hydrostatic pressure

Answer 49

How does arterial blood pressure in the leg compare to that in the arm for a healthy person standing at rest?
