Calculate the heat needed to raise the temperature of a piece of gold that weighs 5.8 g by 8.4°C if the specific heat of gold is 0.13 J/g°C.

q = mass Au x specific heat Au x delta T.

Substitute and turn the crank.

Hmmm, let's see. So you want to know the heat needed to warm up that gold piece, huh? Well, first things first, we need to use a formula:

Q = m * c * ΔT

Where Q represents the heat, m is the mass of the gold (5.8 g in this case), c is the specific heat (0.13 J/g°C), and ΔT is the change in temperature (8.4°C).

Plug in the values we know, and let's calculate the heat:

Q = 5.8 g * 0.13 J/g°C * 8.4°C

Hmm, seems like I've got my calculator all tangled up in clown shoes! Let me fix that.

Alright, let's crunch the numbers:

Q = 5.8 g * 0.13 J/g°C * 8.4°C
Q = 6.7852 J

So it looks like we need approximately 6.79 J of heat to warm up that piece of gold. Keep in mind, this is just an approximation, so don't expect the gold to burst into flames or anything!

To calculate the heat needed to raise the temperature of the gold, you can use the following formula:

Q = m * c * ΔT

where:
Q = heat
m = mass of the gold (in grams)
c = specific heat of gold (in J/g°C)
ΔT = change in temperature (in °C)

Given:
mass of the gold (m) = 5.8 g
specific heat of gold (c) = 0.13 J/g°C
change in temperature (ΔT) = 8.4°C

Substituting the given values into the formula:

Q = (5.8 g) * (0.13 J/g°C) * (8.4°C)

Q = 6.0312 J

Therefore, the heat needed to raise the temperature of the gold by 8.4°C is approximately 6.03 J.

To calculate the heat needed to raise the temperature of a substance, we can use the formula:

Q = m * c * ΔT

where:
Q = heat energy (in Joules)
m = mass of the substance (in grams)
c = specific heat capacity of the substance (in J/g°C)
ΔT = change in temperature (in °C)

In this case, we are given:
m = 5.8 g (mass of gold)
c = 0.13 J/g°C (specific heat of gold)
ΔT = 8.4°C (change in temperature)

Now we can substitute these values into the formula and calculate the heat (Q):

Q = 5.8 g * 0.13 J/g°C * 8.4°C

Q ≈ 6.6808 J

Therefore, the heat needed to raise the temperature of the gold by 8.4°C is approximately 6.6808 Joules.
