Question: In a calorimetry experiment, if 50 g of water is heated from 25 °C to 75 °C, what is the heat absorbed (q) assuming specific heat capacity of water is 4.18 J/g°C?

Options:

  1. 1045 J
  2. 2090 J
  3. 1250 J
  4. 500 J

Correct Answer: 2090 J

Solution: 

q = mcΔT = 50 g × 4.18 J/g°C × (75-25)°C = 1045 J.

Questions & Step-by-Step Solutions

In a calorimetry experiment, if 50 g of water is heated from 25 °C to 75 °C, what is the heat absorbed (q) assuming specific heat capacity of water is 4.18 J/g°C?
  • Step 1: Identify the mass of water (m). In this case, it is 50 grams.
  • Step 2: Identify the specific heat capacity (c) of water. It is given as 4.18 J/g°C.
  • Step 3: Determine the initial temperature (T_initial) and final temperature (T_final) of the water. Here, T_initial is 25 °C and T_final is 75 °C.
  • Step 4: Calculate the change in temperature (ΔT) using the formula ΔT = T_final - T_initial. So, ΔT = 75 °C - 25 °C = 50 °C.
  • Step 5: Use the formula for heat absorbed (q), which is q = mcΔT. Substitute the values: q = 50 g × 4.18 J/g°C × 50 °C.
  • Step 6: Perform the multiplication: 50 g × 4.18 J/g°C = 209 J. Then, multiply 209 J by 50 °C to get q = 1045 J.
  • Calorimetry – The study of heat transfer during physical and chemical processes.
  • Specific Heat Capacity – The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
  • Heat Calculation – Using the formula q = mcΔT to calculate the heat absorbed or released.
