a metal weighing 50.0g absorbs 20.0j of heat when its temperature increases by 150.0°c . what is the specific heat of the metal
nadezda [96]

Answer:

2.677 J/g°C

Explanation:

Quantity of heat required to raise the temperature of the metal,

Q = mc∆T

where m is the mass of the metal, c is the metal's specific heat capacity, and ∆T is the change in temperature that accompanies the heat transfer process

20.0J = 50.0g × c × 150°C

c = 20.0J/(50.0g × 150°C)

c = 2.677 J/g°C

In order to ice to melt it must absorb heat This makes it an blank process.
sveta [45]

Answer: A. Endothermic

Explanation:

In an endothermic reaction, heat is sucked in from the surrounding area by the reactants so that they may use it to react and form new products. This will therefore reduce the temperature in the said surrounding by the amount that the reaction needed.

This is what ice does when it melts. It sucks in the heat surrounding the area and then melts but leaves the area colder. For instance, putting ice in water ensures that the ice melts but because it sucked in the heat from the water to do so, the water gets colder as a result.

Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
Hope this helps and mark as brainliest if you thought it was most helpful :)
