C1 thermal physics Flashcards
what is the definition of energy transferred?
The conversion of one form of energy into another, or the movement of energy from one place to another.
What is the formula for work done
work done = force x change in distance
What is the formula for work done by gas
pressure x ∆v
∆v = change in volume
What is the formula for kinetic energy
1/2mv2
What is the formula for gravitational potential energy
M x G x H
M = mass
G = Gravity 9.81
H = height
What is the formula for thermal energy/energy transferred
Mass x specific heat capacity x change in temperature
What is the formula for elastic potential energy
1/2kx2
What is the formula for power
work done divided by time
What is the formula for efficiency
useful energy output divided by total energy input
what is the formula for the efficiency of heat engine

what is the formula for combined gas law
pv=nrt
what is the formula for combined gas law rearranged for p
p = nrt/v
what is the formula for combined gas law rearranged for v
v = nrt/p
what is the formula for combined gas law rearranged for n
n = pv/rt
what is the formula for combined gas law rearranged for T
t = pv/nr
what is Boyle’s law
p1 v1 = p2 v2
what is gay lussacs law
p1/ t1 = p2/t2
what is Charles law
v1/ t1 = v2/t2
what is Avogadro’s law
v1/ n1 = v2/n2
What is the specific heat capacity definition
amount of energy needed to change one 1kg mass by 1C
what is the specific latent heat triangle formula
mass x specific latent heat
what is the specific latent heat formula
mass
what is the internal energy formula
u = 1.5 x R x T
T = temperature
R = constant 8.3145
what is the first law of thermodynamics
ΔU = Q − W
ΔU is the change in internal energy of a system
Q is the net heat transfer
W is the net work done
what is Bernoulli’s equation?
p1 + 1/2pv^21 + pgh1 + p2 +1/2pv^22 +pgh2
