Answer: mass = 48.47 kg.
Explanation:
Formula : Weight = mg , where m = mass of body , g= acceleration due to gravity .
Given: Weight = 475 N
Substitute all values in formula , we get
Hence, his mass = 48.47 kg.
The metal whose specific heat capacity is close to the obtained value is aluminum.
<h3>What is specific heat capacity</h3>
The specific heat capacity of an object is the heat required to raise a unit mass of the substance by 1 kelvin.
where;
- c is the specific heat capacity
- Δθ is change in temperature
Let the mass of the water = 50 g
mass of the metal for this first trial = 50 g
The heat gained by the water is calculated as follows
Specific heat capacity of the metal for the first trial is calculated as follows;
Heat gained by water = Heat lost by metal
Specific heat capacity of the metal for the second trial;
mass of metal = 200 - mass of water = 150 g
Specific heat capacity of the metal for the third trial;
Specific heat capacity of the metal for the fourth trial;
Specific heat capacity of the metal for the fifth trial;
Average specific heat capacity
The metal whose specific heat capacity is close to the above value is aluminum.
