Flashcards in last test Deck (29):
1

Average kinetic energy of particles in substance

Temperature

2

Celsius scale

0-100

3

Kelvin lowest temperature

-273

4

Total amount of energy of the particles of the substance (kinetic and potential)

Thermal energy

5

Energy transferred from hot to cold

heat energy

6

ways a particle will have kinetic energy (5)

motion of particle-by itself moving around
motion in particle
rotational-bonds will twist and untwist like a spring
oscillating-vibrate back and forth (in particle)
stretching- like a spring

7

2 types of expansion-linear v volume

linear-longer or shorter due to temperature change
volume-as you heat up sides grow

8

heat flow is caused by a change in

temperature

9

q=thermal energy measured in

Joules

10

Q depends on 3 quantites

mass
temperature
specific heat

11

When phase change occurs the ___ changes (stretches or breaks) but the ___ does not change

bond, temperature

12

solid to gas

sublimation

13

gas to solid

deposition

14

how would you know which substance would boil first?

specific heat capacity

15

isovaric

constant pressure

16

isothermic

constant temperature Q=w

17

adiabatic

no change in heat Δu=w

18

isovolumetric

constant volume Δinternal energy=heat
Δu=Q

19

3 things to control amount of thermal energy

conduction (requires matter) (direct contact hot to cold)
convection (requires matter) (must be fluid-liquid or gas)
radiation (does not require matter)

20

convection only occurs when

cold is on top and warm is on bottom

21

Radiation measured in

Watt

22

SMOOTH FLOW, VELOCITY IS CONSTANT THROUGHOUT FLUID

LAMINAR

23

IRREGULAR FLOW WITH TINY WHIRLPOOLS

TURBULENT

24

THE RECIPROCOL OF THE FREQUENCY

TIME PERIOD

25

TIME IT TAKES TO COMPLETE ONE CYCLE OF A REPEATING EVENT

TIME PERIOD

26

NUMBER OF OCCURANCES PER UNIT TIME

FREQUENCY

27

THE AREAS OF NO DISPLACEMENT

NODES

28

CONSTRUCTIVE INTERFERANCE CAUSES

ANTI-NODES

29

DECONSTRUCTIVE INTERFERANCE CAUSES

NODES
