How many calories are required to heat 10 ml of water from 25 degrees Celsius to 35 degrees Celsius?
To calculate the number of calories required to heat water, you can use the specific heat capacity of water, which is approximately 1 calorie per gram per degree Celsius.
First, convert the volume of water from milliliters to grams. This can be done by assuming that 1 milliliter of water is equivalent to 1 gram.
So, 10 ml of water is equal to 10 grams.
Next, calculate the change in temperature:
ΔT = Final temperature - Initial temperature
= 35°C - 25°C
= 10°C
Now, use the specific heat capacity of water to calculate the calories required:
Q = mcΔT
= 10 grams * 1 calorie/gram/°C * 10°C
= 100 calories
Therefore, 100 calories are required to heat 10 ml of water from 25 degrees Celsius to 35 degrees Celsius.
To determine the number of calories required to heat 10 ml of water from 25 degrees Celsius to 35 degrees Celsius, you need to use the specific heat capacity of water.
The specific heat capacity of water is approximately 1 calorie per gram per degree Celsius (1 cal/g°C). However, since you have 10 ml of water, you need to convert this to grams before calculating the number of calories.
First, you need to convert the volume of water (10 ml) to grams. The density of water is approximately 1 gram per milliliter (1 g/ml). Therefore, 10 ml of water is equal to 10 grams.
Next, you calculate the temperature change by subtracting the initial temperature (25°C) from the final temperature (35°C). In this case, the temperature change is 35°C - 25°C = 10°C.
Now, you can calculate the number of calories required using the formula:
Calories = mass (in grams) × specific heat capacity (1 cal/g°C) × temperature change (in °C)
Calories = 10 g × 1 cal/g°C × 10 °C = 100 calories
Therefore, it would take 100 calories to heat 10 ml of water from 25 degrees Celsius to 35 degrees Celsius.
Note: It's important to use calorie units for this calculation, as the specific heat capacity of water is defined in calories per gram per degree Celsius.
