<u>Answer:</u>
Work done done by a system on its environment is W=40 Joules
<u>Explanation:</u>
<u>Given:</u>
Ideal gas is maintained at a constant pressure 
Change in Volume 
<u>To find:</u>
Work done by a system during an Isobaric Process
<u>Solution:</u>
In a Isobaric Process, constant pressure is maintained,
According to the formula,
work done 
Substitute the values of pressure and change in volume in the above formula,
<u>Result:</u>
Work done done by a system W= -40 Joules
False, it does. Hope this helped!
Answer:
3.39 mins.
10m/s multiplied by 6 equals to 60 seconds or 1 minute
<span>Acceleration is the rate of
change of the velocity of an object that is moving. This value is a result of
all the forces that is acting on an object which is described by Newton's
second law of motion. Calculations of such is straightforward, if we are given
the final velocity, the initial velocity and the total time interval. However, we are not given these values. We are only left by using the kinematic equation expressed as:
d = v0t + at^2/2
We cancel the term with v0 since it is initially at rest,
d = at^2/2
44 = a(6.2)^2/2
a = 2.3 m/s^2

Answer:
7.55 g
Explanation:
Heat of fusion = 333kj/kg
Heat capacity, c = 4190 j/kg /k
Heat capacity in j/g /k = 0.4190
Let the Number of grams of ice that will melt = n
Number of grams * heat of fusion = heat capacity * temperature change
n * 0.333 = 0.419 * (6-0)
0.333n = 2.514
n = 2.514 / 0.333
n = 7.5495
n = 7.55 gram
Hence, the number of gram of ice that will melt is 7.55 grams
