Can you look at the picture and tell me that answer ? you

The answer is choice (1).

In case you're interested in the solution for future reference:

-- Density = (mass) / (volume)

-- The scale shows that the mass of the sample is 60 grams.

-- The graduated cylinder has 24 mL in it without the sample.
The graduated cylinder has 34 mL in it with the sample.
The volume of the sample is (34mL - 24mL) = 10 mL .

-- Density = mass/volume = 60g / 10mL = 6 g/mL

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
