Answer:

Static Electricity.

Explanation:

Static electricity is defined as 'an electric charge that has built up on an insulated body, often due to friction.' <u> It is an outcome of the disparity among the positive, as well as, negative charges residing in a body</u> or object and causes the charge to build up on the surface of the body. The accumulation of electric charges on the objects like wool, hair, silk, plastic, etc. causes them to possess static electricity. These charges stay on the surface until it is discharged or released through a source. Thus, <u>'static electricity</u>' is the correct answer.

A slice of pizza has 500 kcal. If we could burn the pizza and use all the heat to warm a 50-L container of cold water, what woul
gayaneshka [121]

Answer:

10°C  

Explanation:

Heat gain by water = Heat lost by the slice of pizza

Thus,    

m_{water}\times C_{water}\times \Delta T=Q

<u>For water:  </u>

Volume = 50.0 L

Density of water= 1 kg/L  

So, mass of the water:  

Mass\ of\ water=Density \times {Volume\ of\ water}  

Mass\ of\ water=1 kg/L \times {50.0\ L}  

Mass of water  = 50 kg

Specific heat of water = 1 kcal/kg°C  

ΔT = ?

For slice of pizza:  

Q = 500 kcal

So,

50\times 1\times \Delta T=500  

ΔT = 10°C  

Increase in temperature = 10°C
