50g of an unknown metal at 100.0 degrees celsius is placed into 150g of water at 20.0 degrees Celsius and the final temperature of the metal and water is 23.3 degrees Celsius. What is the specific heat of the metal?

0.5395 J/g°C

Explanation:

We are given he following;

We are required to determine the specific heat of the metal

First we determine heat gained by water;

Quantity of heat = Mass × change in temperature × specific heat

specific heat of water is 4.18 J/g°C

Therefore;

Heat =  150 g × 3.3°C × 4.18 J/g°C

         = 2069.1 Joules

Second, we determine the heat lost by the unknown metal

Taking the specific heat f the metal to be x

Then;

Heat = 50 g × 76.7 °C × x

        = 3835x joules

But;

Heat lost = heat gained

Therefore;

3835x = 2069.1 J

       x = 0.5395 J/g°C

Thus, the specific heat of the unknown metal is 0.5395 J/g°C

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
