Answer:
1.
- Heat capacity is defined as the total amount of heat required to increase the temperature of a substance in 1°C.
- Specific heat is defined as the total amount of heat required to increase the temperature of a substance in 1°C per unit mass. Hence this property depends of the mass of the substance.
- Latent heat is the amount of energy absorbed or released by a substance in a phase change (physical change) without a change in temperature.
2.
- Degrees of freedom is the number of parameters that define the configuration of a system. For example, in a system with we want to know about the dynamic in the three dimension x,y,z and also about the rotation around a fixed axe we have four degrees of freedom.
- Equipartition theorem relates the temperature of a system with the average energy of the system (this average is taken for those degrees of freedom that appears quadratically).

Answer: 345
Step-by-step explanation:
15% + 100% = 115%
100%.......300£
115%..........x£
x = 115*300/100
x= 345
| q | > n
1. q + n < 0
2. q + n - n < 0 - n
3. q < -n, where q is negative, and n is positive. Therefore, | q | > n.
Well, think about it. If q + n is less than zero (negative), what kind of relationship can you assume about q and n?
Answer:
y=-9/8x+7
Step-by-step explanation:
When finding slope from the graph, the coordinate that has a zero where x is supposed to be is the y-intercept. To put it into slope-intercept form it is important to remember y=mx+b. B is the y-intercept so you'll take the y value and put it where b is. So in this case you'll have y=mx+7. To find the slope you have to find the distance between the two coordinates. So you'll see how many times you go up from -2 to 7, 9 times. Then you calculate how many times you go over from 8 to 0, 8 times. The 8 and the 9 are the two values of slope. When forming the slope you put the rise over the run. Or in other words, you put how many times you go up/down over how many times you go left/right. To determine if the slope is negative or positive you look at the line and if the values are getting smaller or the line is going from left to right, then it is negative. If the values are getting bigger or the line is going from right to left, then it is positive. In this case the values are getting smaller and the line is going from left to right which means this slope is negative. So you add a negative to 9/8 and replace m with what you just got (the slope). Your answer should look like this, y=-9/8x+7.
