Answer:
in this situation I would a little bold
Explanation:
first I don't know what extinguisher I would use pretty much any that helps with fires. I'll back people up, take the hood and put it on the small fire that way it will light out more and if I open the hood and there still a little fire I would use the extinguisher and no one gets hurt :)
Answer: 16700 Joules
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
![Q=m\times c\times \Delta T](https://tex.z-dn.net/?f=Q%3Dm%5Ctimes%20c%5Ctimes%20%5CDelta%20T)
Q = Heat absorbed = ?
m = mass of sand = 2 kg
c = heat capacity = ![835J/kg^0C](https://tex.z-dn.net/?f=835J%2Fkg%5E0C)
Initial temperature =
= ![40^0C](https://tex.z-dn.net/?f=40%5E0C)
Final temperature=
= ![50^0C](https://tex.z-dn.net/?f=50%5E0C)
Change in temperature ,![\Delta T=T_f-T_i=(50-40)^0C=10^0C](https://tex.z-dn.net/?f=%5CDelta%20T%3DT_f-T_i%3D%2850-40%29%5E0C%3D10%5E0C)
Putting in the values, we get:
![Q=2kg\times 835J/kg^0C\times 10^0C](https://tex.z-dn.net/?f=Q%3D2kg%5Ctimes%20835J%2Fkg%5E0C%5Ctimes%2010%5E0C)
![Q=16700J](https://tex.z-dn.net/?f=Q%3D16700J)
16700 J of energy must be added to a 2-kilogram pile of it to increase its temperature from 40°C to 50°C
