Answer:
The change in T° is 47.1 °C
Explanation:
Calorimetry formula to solve this:
Q = m . C . ΔT
We replace the data gien:
635 J = 3.50×10⁻² kg . 0.385 J/g°C . ΔT
In units of C, we have g and the mass (m) is in kg. So let's convert it from kg to g → 3.50×10⁻² kg . 1000 g / 1kg = 35 g. Now we can determine the ΔT:
635 J = 35 g . 0.385 J/g°C . ΔT
635 J / 35 g . 0.385 J/g°C = ΔT
47.1°C = ΔT
Answer:
The change in temperature is 47.12 °C
Explanation:
Step 1: Data given
Mass of copper = 3.50 * 10^-2 kg = 35 grams
Energy = 635 J
Specific heat of copper = 0.385 J/g°C
Step 2: Calculate change in temperature
Q = m*c*ΔT
⇒ Q = the energy required = 635 J
⇒ m = the mass of copper = 35 grams
⇒ c = the specific heat of copper= 0.385 J/g°C
⇒ ΔT = Change in temperature = TO BE DETERMINED
635 J = 35g * 0.385 J/g°C * ΔT
ΔT = 635 / (35*0.385)
ΔT = 47.12 °C
The change in temperature is 47.12 °C
