How much heat does it take to raise the temperature of 0.10kg of aluminum by 25°C

Heat required to raise the temperature of aluminium is 2250 J

Explanation:

Heat required to raise the temperature of the given substance is

here we know that

m = 0.10 kg

specific heat capacity of the metal is

s = 900 J/kg C

change in temperature of the metal is 25 degree

Now we have

c) up

hope this

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
