How do you convert energy into to joules (can you please give me an example with showing me your i.e how you did it, in full detail)
How do you find specific heat numbers?
Your questions beg for amplification. Please expand. Energy is measured in joules (IN SI), what do you mean convert energy into joules? How does one find specific heat numbers? It depends on what is given. Please expand these questions.
The qeustion asked is Suppose you use 135 calories of energy to perform a task, how many joules have you used? See, I don't want the answer, just the steps leading me up to the answer, like how to figure this problem out wiht out using a coverting system.
The other question is figured out, you know the one about specific heat, it was in my book all along.
To convert energy into joules, you need to know the appropriate conversion factor. In this case, 1 calorie is equal to 4.184 joules.
For example, let's say you have 135 calories of energy. To convert this into joules, you can multiply the calories by the conversion factor:
135 calories * 4.184 joules/calorie = 564.04 joules
So, if you use 135 calories of energy, you have used approximately 564.04 joules.
As for finding specific heat numbers, specific heat is the amount of heat required to raise the temperature of a substance by 1 degree Celsius (or 1 Kelvin). The specific heat of a substance can be found experimentally or it can be given in reference books or tables.
If you have the specific heat of a substance and you know the mass and change in temperature, you can use the formula:
q = m * c * ΔT
where q is the heat energy absorbed or released, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature.
For example, if you have a sample of water with a mass of 100 grams and the specific heat of water is 4.184 J/g·°C, and you want to calculate the heat energy required to raise the temperature by 10 degrees Celsius, you can substitute the values into the formula:
q = (100 g) * (4.184 J/g·°C) * (10 °C) = 4184 J
Therefore, the heat energy required is 4184 joules.
Note that it's important to use consistent units throughout the calculation to ensure accurate results.
I'm glad you found the information about specific heat in your book! If you have any other questions or need clarification, feel free to ask.
