Verified step by step guidance1
Understand the concept of specific heat capacity: The specific heat capacity is the amount of energy required to raise the temperature of one gram of a substance by one degree Celsius.
Identify the specific heat capacity of water: For water, the specific heat capacity is 1 calorie per gram per degree Celsius.
Convert calories to joules if needed: Since 1 calorie is equivalent to approximately 4.184 joules, you can convert between these units if necessary.
Compare the given options: Evaluate the options provided (0.239 calories, 1 calorie, 1 joule, 4.18 joules) against the known specific heat capacity of water.
Select the correct answer: Based on the specific heat capacity of water, determine which option correctly represents the energy required to raise the temperature of one gram of water by one degree Celsius.
