What is the Amount of Heat Required to Raise the Temperature of Water?

Understanding the Problem

To solve this problem, we need to apply the concept of specific heat capacity, which is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius. The specific heat capacity of water is 1 calorie per gram per degree Celsius (cal/g°C).

Given Information

  • Mass of water (m) = 50.0 g
  • Initial temperature (T1) = 50.0°C
  • Final temperature (T2) = 105°C
  • Specific heat capacity of water (c) = 1 cal/g°C

Step 1: Calculate the Temperature Change

The temperature change (ΔT) is the difference between the final and initial temperatures.

ΔT = T2 - T1 = 105°C - 50.0°C = 55.0°C

Step 2: Calculate the Amount of Heat Required

The amount of heat (Q) required to raise the temperature of the water is given by the formula:

Q = mcΔT

where m is the mass of water, c is the specific heat capacity of water, and ΔT is the temperature change.

Substituting the given values, we get:

Q = (50.0 g) × (1 cal/g°C) × (55.0°C) = 2750 cal

However, this is not the only possible answer. We need to consider the options provided and determine which one is correct.

Analyzing the Options

A. 2.90×1042.90 \times 10^4 cal B. 7.83×1047.83 \times 10^4 cal C. 2.96×1042.96 \times 10^4 cal

To determine which option is correct, we need to calculate the amount of heat required using the formula:

Q = mcΔT

Substituting the given values, we get:

Q = (50.0 g) × (1 cal/g°C) × (55.0°C) = 2750 cal

However, we need to express this value in scientific notation. To do this, we can multiply the value by 10^3, since 2750 = 2.75 × 10^3.
