Q

Work

A

the energy used to cause an object to move against a force
(w)= the energy transferred when a force moves an object

Q

Electrostatic potential energy

A

Eeb

  • interactions between charged particles
  • proportional to the electrical charges on the two interacting objects, Q1 and Q2, divided by distance, d, separating them.

Eed= kQ1xQ2/d

k, constant, times electrical charges of object 1, Q1, times electrical charge of object 2, Q2, all divided by distance, d.

Q

system

Study These Flashcards
A

portion of energy change that we focus on

-in a chemical reaction this would be the reactants and products

25
surroundings
everything else that is involved in an energy change | -in a chemical equation the surroundings would be the container and everything beyond it
26
open system
a system in which matter and energy can be exchanged with the surroundings - An uncovered pot of boiling water on a stove. - heat comes into the system from the stove, and water is released to the surroundings as steam
27
closed systems
Systems that can exchange energy but not matter with their surroundings - most readily study in thermochemistry - mixture of H2 and O2 in a cylinder fitted with a piston. - System: Hydrogen and Oxygen - Surroundings: everything beyond them - if they react to form water energy is liberated but no matter is added. Energy however is transferred to the surroundings.
28
isolated system
one in which neither energy nor matter can be exchanged with the surroundings. - Thermos containing coffee - not perfectly isolated however because the coffee does eventually cool.
29
force
any push or pull exerted on an object. | F
30
mass of object (m) times gravitational constant (g) equals what? m x g = ?
Force (F)
31
Gravitational constant (g) =
9.8 m/s^2
32
First law of Thermodynamics
Energy is conserved (cannot be created nor destroyed)
33
Plank's constant
h= 6.626x10^-34 J-s
34
λ
Lambda=Wavelength=meters
35
How to determine wavelength or frequency
c=λxν | Speed of light= lambda x nu
36
ν
Nu= frequency= s^-1=Hz
37
s^-1
Hz
38
c
Speed of light= 3.00x10^8 m/s
39
E
Energy in J of one quantum of electromagnetic radiation
40
Calculating E using v(nu)
E=hxv | Energy of wave= planks constant x frequency
41
Light is considered what type of radiation?
Electromagnetic radiation
42
How do you find E using wavelength directly
E=hc/λ | Energy = (plank x speed of light) / wavelength
43
n stands for
Principle quantum number | i.e. n1, n2, n3, n4
44
R
Rydberg's constant=1.097x10^-2 nm-1
45
Calculating E of a principle quantum number(n)
(-hcR)(1/n^2) | -plank x speed of light x rynberg)x(1/ principle quantum #^2
46
Calculating wavelength using given mass and velocity
λ=h/mv | λ=plank/mass x velocity
47
Letter representing values of l
Value of l, | 0=s, 1=p, 2=d, 3=f
48
1Lxatm=
1L x atm= 101.3 J
49
ΔE
Change in energy = q + w
50
q=
ΔH
51
w=
``` Work = -PΔV Work = -pressure x change in volume ``` ``` Work= F x d Work= force x distance ```
52
F=
Newtons (N)
53
d=
meters(m)
54
q is given as
J
55
1N x m is equal to
1J
56
How to get change in heat ΔH
ΔH=ΔE+PΔV
57
C with subscript s is
Specific heat.
58
Using specific heat to calculate heat(q)
q=CxmxΔT | Heat(J) = Specific heat(C) x mass(g) x Δ Temperature(K)
