1) In the boxes below, draw the model given in the simulation and draw a model of the molecules in an object when the object
1 answer:
The molecules of the cold element are going to be closer together and still than the molecules of the hot element because the heat energy causes the molecules to be stimulated and to move.
<h3>How do molecules act at different temperatures?</h3>
In the image you can see the behavior of the molecules when they are in different environments. On the right you see the cold molecules and on the left the hot molecules that are characterized by the following characteristics:
Cold molecules:
- Molecules together.
- Molecules with little movement.
Hot molecules:
- Separate molecules.
- Molecules with active movement.
A simple example to understand this behavior of molecules is water because:
- When water is frozen its molecules are almost static and close together.
- When the water is liquid and it is heated, the molecules move and that is why the water has bubbles, its molecules are separated.

Answer : The number of moles of gas inside the car is, 105.0 mole.
Explanation :
To calculate the moles of gas we are using ideal gas equation.
where,
P = Pressure of gas = 98.5 kPa = 0.972 atm (1 atm = 101.3 kPa)
V = Volume of gas = 2600 L
n = number of moles of gas = ?
R = Gas constant =
T = Temperature of gas =
Now put all the given values in above equation, we get:
Therefore, the number of moles of gas inside the car is, 105.0 mole.
Answer:
Q = 5254.39 J
Explanation:
Given that,
Mass of ethanol, m = 68.8 g
The temperature increases from 40.0°C to 71.3°C.
The specific heat of ethanol is 2.44 j/g°C
We need to find the heat absorbed by the ethanol. We know that the heat absorbed due to the change in temperature is given by :
Put all the values,
So, 5254.39 J of heat is absorbed by Ethanol.
