Answer:
star 3
Explanation:
the color determines the fusion in between
Answer:
For these types of questions the equation that we must take into account is that:
T = PxV (where T is the temperature, P is the pressure and V is the volume) this equation is described as we consider that this is the value N and R is 1, therefore it is not necessary to explain them now.
Explanation:
The quoted equation refers to Boyle's Law, in this law we can explain that the volume increases if the pressure decreases and if the temperature also increases, if the pressure increases and the volume decreases this means that the gas is compressing assuming that the temperature is constant
<u>Answer:</u> The change in temperature is 84.7°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
![q=mc\Delta T](https://tex.z-dn.net/?f=q%3Dmc%5CDelta%20T)
where,
q = heat absorbed = 1 kCal = 1000 Cal (Conversion factor: 1 kCal = 1000 Cal)
m = mass of steel = 100 g
c = specific heat capacity of steel = 0.118 Cal/g.°C
= change in temperature = ?
Putting values in above equation, we get:
![1000Cal=100g\times 0.118Cal/g.^oC\times \Delta T\\\\\Delta T=\frac{1000}{100\times 0.118}=84.7^oC](https://tex.z-dn.net/?f=1000Cal%3D100g%5Ctimes%200.118Cal%2Fg.%5EoC%5Ctimes%20%5CDelta%20T%5C%5C%5C%5C%5CDelta%20T%3D%5Cfrac%7B1000%7D%7B100%5Ctimes%200.118%7D%3D84.7%5EoC)
Hence, the change in temperature is 84.7°C
