Two samples of hot unknown metals of equal temperatures are dropped in separate containers of water at 30 degrees Celsius. The final temperature of sample A is 33.5 degrees, and the final temperature of sample B is 31.8 degrees. Which metal sample had the highest specific heat?

Sample B has the highest specific heat

Explanation:

Specific heat of a material is defined as the heat necessary to increase in the temperature of 1g of material in 1°C.

The material with the highest specific heat requires more energy to increase its temperature.

In the problem, sample A and B are under the same amount of energy but sample A increases more its temperature. That means sample A has the lowest specific heat and:

Sample B has the highest specific heat

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

The answer is d for this question
