How much heat is needed to raise the temperature of a 100.0g of water by 85.0 c?
KatRina [158]

Answer:

35.7kJ

Explanation:

we can calculate the amount of heat energy required , using this formula

Q = mcθ

where.

Q = heat energy (Joules, J)  

m = mass of a substance (kg)  

c = specific heat capacity (units Jkg^{-1} C^{-1})

θ  = change in temperature (Celcius,C or Kelvin K)

Assume Specific heat capacity (c) of water =4200Jkg^{-1} C^{-1}

mass =0.1 kg

Q=0.1 kg*4200Jkg^{-1} C^{-1}*85C\\=35700J\\=35.7kJ

What happens in an electromagnet if the core is partially air and partially iron when it is energized?
Xelga [282]
IT WOULD act like an electromagnet even now
this same thing happens when we make use of solenoids. we have a wire wound around a hollow pipe , and that pipe would have air in it . as there is no natural vaccum here, the air will get ionised.. spreading charges .. around itself..
