You have 17 grams of water and you increase the temperature by 15 degrees Celsius how many joules did this take?a. 255
b. 1067
c. 1.13
d. 63

Answers

Answer 1
Answer:

Answer: the correct answer is option(d).

Explanation:

Energy required ,Q= ?

Mass of water , m = 17 grams

Temperature difference or\Delta T = 15 °C

Specific heat value of water = 4.186 J/g °C

Q=mc\Delta T=17* 4.186 J/g^oC* 15^oC=1,067.43 J\approx 1,067 J

From the given value the , nearest value to to our calculated answer is 1067 J that option (b).

Hence, the correct answer is option (d).

2. Correspondence Theory (Theory of corespondence)

Based on this theory, a knowledge considered to be true if the knowledge of having a relationship with a reality that is true. This theory is based on the empirical fact that knowledge is true if there are facts that support that is true knowledge. Thus the truth here is based on inductive inference.
