Answer: 1896.55J/kg°C

Explanation:

The quantity of Heat Energy (Q) required to heat a material depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = 1320 joules

Mass of material = 5.61kg

C = ? (let unknown value be Z)

Φ = 0.124°C

Then, Q = MCΦ

1320J = 5.61kg x Z x 0.124°C

1320J = 0.696kg°C x Z

Z = (1320J / 0.696kg°C)

Z = 1896.55 J/kg°C

Thus, the specific heat of the material is 1896.55J/kg°C

Answer:

1897.53J/Kg°C

Explanation:

Data obtained from the question include:

M (mass of material) = 5.61 kg

ΔT ( change in temperature) = 0.124°C

Q ( heat) = 1320 J

C (specific heat capacity of the material) =?

Using the formula Q = MCΔT, the specific heat capacity of the material can be obtained as follow:

Q = MCΔT

C = Q / MΔT

C = 1320J/ (5.61 kg x 0.124°C)

C = 1897.53J/Kg°C

Therefore, the specific heat capacity of the material is 1897.53J/Kg°C

Why do you think a clothes dryer requires a 220-volt outlet, while a toaster only requires a 110-volt outlet?
hammer [34]

A toaster needs a 110-volt outlet because it doesn’t need too much electricity.  Electricity can be converted to heat, and toaster only needs to be heated and nothing else that requires extra electricity while clothes dyer requires higher voltage because it needs more effort and electricity in order to do its function.

Which occupies mrs space, 3m cubed or 100ft cubed
Slav-nsk [51]

The question is somewhat ambiguous.

-- It's hard to tell whether it's asking about  '3 cubic meters'
or  (3m)³ which is actually 27 cubic meters.

-- It's hard to tell whether it's asking about    '100 cubic feet'
or  (100 ft)³ which is actually 1 million cubic feet.

I'm going to make an assumption, and then proceed to
answer the question that I have invented.
I'm going to assume that the question is referring to
'three cubic meters'  and  'one hundred cubic feet' .

OK.  We'll obviously need to convert some units here.
I've decided to convert the meters into feet.

For 1 meter, I always use    3.28084 feet.

Then (1 meter)³ = 1 cubic meter = (3.28084 ft)³ = 35.31 cubic feet.

So 3 cubic meters = (3 x 35.31 cubic feet) =  105.9 cubic feet.

That's more volume than  100 cubic feet.
