Answer : The specific heat of tungsten is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of tungsten = ?
= specific heat of water =
= mass of tungsten = 19.5 g
= mass of water = 78.5 g
= final temperature =
= initial temperature of tungsten =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat of tungsten is,

Explanation:
Answer:
78.75g
Explanation:
The density of diamond is the mass of diamond per unit of its volume. The density of a substance is calculated using the formula:
Density (g/cm^3) = mass (g) / volume (cm^3)
According to the question, the density of diamond= 3.15g/cm^3, volume of diamond= 25cm^3, mass = ?
Hence, to calculate the mass, we say;
Mass = Volume × density
Mass = 25 × 3.15
Mass = 78.75
Therefore, the mass of diamond is 78.75grams.
1.49 moles of Al will be produced. Hope this helps you.
a, c, and d are all chemical properties because they give information about how a substance will behave in the given reaction, and can’t be found without the substance undergoing some sort of chemical reaction. b, on the other hand, is a physical property—it can be determined without changing the substance’s chemical composition.
