Answer:
The answer is
<h2>2.63 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of silver = 0.25 cm³
density = 10.5 g/cm³
The mass is
mass = 10.5 × 0.25 = 2.625
We have the final answer as
<h3>2.63 g</h3>

Answer:
A
Explanation:
The specific heat capacity can be defined as the amount of energy that is required to raise the temperature of 1kg of a body by exactly 1k.
When calculating the amount of heat required, we usually employ the use of the formula that relates the amount of heat, the mass of the body, the specific heat capacity and the temperature change. The amount of heat is represented by H, the mass of the body by m, the heat capacity by C while the temperature difference is represented by delta T
B. When melted, the chocolate will take the shape of the bowl.
Explanation:
The chocolate chips are heated in the bowl, they will assume the shape of the bowl or container they are placed in.
- They simply undergo a phase change from solids to liquids.
- Solids generally have fixed volume with their rigid shapes.
- Liquids and gases takes up the shape of the container they are placed in.
- Baring no loss of chocolate, the weight will remain the same because weight is function of mass and gravity. Gravity will remain the same, and the amount of matter, the mass will also be the same.
