Answer:
the heat exchange between the system and the surrounding medium
Explanation:
The first law of thermodynamics states that: "Energy can neither be created nor destroyed, but can convert from one form to another"
It is represented mathematically as:
<span>Δ e=q-w
where:</span>
<span>Δ e is the total change in the system's internal energy
q is </span><span>the heat exchange between the system and the surrounding medium
w is the work done either on the system or by the system
Hope this helps :)

Answer:
Explanation:
we know that specific heat is the amount of heat required to raise the temperature of substance by one degree mathmeticaly
Q=mcΔT
ΔT=T2-T1
ΔT=26.8-10.2=16.6
C for water is 4.184
therefore
Q=1.00*4.184*16.6
Q=69.4 j
now we have to covert joule into calorie
1 calorie =4.2 j
x calorie=69.4 j/2
so 69.4 j =34.7 calorie thats why 34.7 calorie heat is required to raise the temperature of water from 10.2 to 26.8 degree celsius
There's a total of 3 colors, the percent will add up to 100%
100%-50%(red)= 50%
50%-10%(blue)=40%
There is a 40% chance it will land on green
Answer is: volume of helium is 244.72 liters.
m(He) = 43.7 g.
n(He) = m(He) ÷ M(He).
n(He) = 43.7 g ÷ 4 g/mol.
n(He) = 10.925 mol.
V(He) = n(He) · n(He).
V(He) = 10.925 mol · 22.4 L/mol.
V(He) = 244.72 L.
Vm - molar volume at STP.
n - amount of substance.
