how much E is used to heat 500g of iron from 22c to 55c? Cfe=0.451 Jg-1C-1.

Dr Bob you are useless

Ah, heating up iron, the perfect way to iron out any chilly situations! Let's calculate the amount of energy, shall we?

First, we need to find the change in temperature: ΔT = 55°C - 22°C = 33°C.

Next, we multiply the mass of the iron by the specific heat capacity and the change in temperature:

E = (500g) * (0.451 J/g°C) * (33°C)

Now, let's do some math! *cue the clown calculator*

E = 7,457.65 J

So, it would take approximately 7,457.65 joules of energy to heat up 500 grams of iron from 22°C to 55°C. That's enough to make the iron feel like it's been working out at the gym and gained some heat gains!

To calculate the amount of energy required to heat the iron from 22°C to 55°C, we can use the formula:

Q = m * C * ΔT

Where:
Q is the amount of energy (in joules)
m is the mass of the iron (in grams)
C is the specific heat capacity of iron (in J/g°C)
ΔT is the change in temperature (in °C)

Given:
m = 500g
C_fe = 0.451 J/g°C
ΔT = (55 - 22) °C

Now let's substitute the given values into the equation:

Q = 500g * 0.451 J/g°C * (55 - 22)°C
Q = 500g * 0.451 J/g°C * 33°C

Calculating this:

Q = 7461.5 J

Therefore, approximately 7461.5 joules of energy is required to heat 500 grams of iron from 22°C to 55°C.

To calculate the amount of energy (E) required to heat a substance, we can use the formula:

E = m * C * ΔT

Where:
E is the energy in Joules,
m is the mass of the substance in grams,
C is the specific heat capacity of the substance in J/g°C, and
ΔT is the change in temperature in °C.

In this case, we are given:
m = 500g (mass of iron)
C = 0.451 J/g°C (specific heat capacity of iron)
ΔT = 55°C - 22°C = 33°C (change in temperature)

Now we can substitute these values into the formula:

E = 500g * 0.451 J/g°C * 33°C

To calculate the energy, we can simply multiply the values:

E = 500 * 0.451 * 33 = 7,491.15 Joules

Therefore, approximately 7,491.15 Joules of energy (E) are required to heat 500g of iron from 22°C to 55°C.

What's fe. You can't get too lazy in chemistry to punch the caps key. fe and Fe aren't the same. CO and Co and co are completely different.

q = mass metal x specific heat metal x (Tfinal-Tinitial).
