7. What initial volume of water vapor would have been present at 310 K if the volume now

Chemistry
1 answer:
Alexxx [7]3 years ago
6 0

Answer:

206.3cm³

     

Explanation:

Given parameters:

Initial temperature  = 310K

Final volume  = 360cm³

Final temperature  = 541K

Unknown:

Initial volume  = ?

Solution:

To solve this problem we apply the Charles's law which states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".

  Mathematically;

     \frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }

V and T are volume and temperature

1 and 2 are initial and final states

 Insert the parameters and solve for V₁;

                    \frac{V_{1} }{310}  = \frac{360}{541}  

                    V₁   = 206.3cm³

How many joules of heat is lost when a 64 g piece of copper cools from 375 oC to 26 oC? The specific heat of copper is 0.38 J/go
Svetlanka [38]

Answer: 8500 J lost or -8500 J

Explanation:

q=cmt

t=375-26

t=349

q=0.38(64)(349)

q=8487.68 J

Answer must have 2 sig figs, which means it rounds to 8500 J.

Define the term inertia
n200080 [17]

Answer:

Explanation:

Enertia is an integral part of Newton's first law of motion.

It is the tendency of an object to <u>stay at rest</u> or <u>to continue moving</u> until and unless <u>any external unbalanced force</u>, (like, applied force or force of tension or frictional force ) is applied to either move it from rest or change its speed(in other words, accelerate it!!).

Example below, is of ball at rest (fig1) and if this ball is moving straight on a frictionless surface(like ice) it will keep moving!! until, we push it or pull it.
