If you wanted to find the area of the hot filament in a light bulb, you would have to know the temperature (determinable from th
Sladkaya [172]

Answer:

To find out the area of the hot filament of a light bulb, you would need to know the temperature, the power input, the Stefan-Boltzmann constant and <u>Emissivity of the Filament</u>.

Explanation:

The emissive power of a light bulb can be given by the following formula:

E = σεAT⁴

where,

E = Power Input or Emissive Power

σ = Stefan-Boltzmann constant

ε = Emissivity

A = Area

T = Absolute Temperature

Therefore,

A = E/σεT⁴

So, to find out the area of the hot filament of a light bulb, you would need to know the temperature, the power input, the Stefan-Boltzmann constant and <u>Emissivity of the Filament</u>.

0.5000 kg of water at 35.00 degrees Celsius is cooled, with the removal of 6.300 E4 J of heat. What is the final temperature of
MArishka [77]

Answer:

65.1 °C

Explanation:

m = mass of the water = 0.5 kg

T_{i} = initial temperature of water = 35.00 °C

T_{f} = final temperature of water

c = specific heat of water = 4186 J/(kg °C)

Q = Amount of heat removed from water = 6.3 x 10⁴ J

Amount of heat removed from water is given as

Q = m c (T_{f} - T_{i})

Inserting the values

6.3 x 10⁴ = (0.5) (4186) (T_{f} - 35.00)

T_{f} = 65.1 °C
