It would be CH2! you’re just simplifying C4H8, 4 can go into C4 1 time (so we just say C) and 4 can go into H8 2 times (H2)
Answer:
A. 140,800 J
Explanation:
Specific heat of a material is defined as the amount of energy required to increase in 1°C 1kg of the material. <em>For wood there are required 1760J perkg per °C.</em>
The equation is:
Q = C*m*ΔT
<em>Where Q is heat in Joules,</em>
<em>C is specific heat (1760J/kg°C),</em>
<em>m is mass (2kg)</em>
<em>ΔT is change in temperature (50°C - 10°C = 40°C)</em>
Replacing:
Q = 1760J/kg°C*2kg*40°C
Q = 140800J
Right option is:
<h3>A. 140,800 J

Answer:
maybe try 4.002602, good luck
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.
