Given 10.8 grams of substance y, if the substance absorbs 231 kilojoules of energy and the specific heat of the substance is 6.55 j/g·°c, what is the change in temperature?

Answer : The change in temperature will be,

Explanation :

Formula used :

where,

Q = heat absorb = 231 kJ = 231000 J     (1 kJ = 1000 J)

m = mass of substance Y = 10.8 g

c = specific heat of substance =

= change in temperature = ?

Now put all the given value in the above formula, we get:

Therefore, the change in temperature will be,

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
