Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 *
cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π *
*l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π *
*l
= 
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
=
*
= 
Answer:
Peroxide is a polyatomic ion consisting of two bonded oxygen atoms. This ion can form a compound with another atom,one of which is hydrogen Peroxide.
Typically two oxygen atoms make a neutral compound, which is oxygen gas. Peroxide can be written as 0-22
Answer:
The final temperature of the water is 28.98 degree Celsius.
Explanation:
It is given that,
Mass of sample of water, m = 52 grams
Initial temperature, 
Heat absorbed, 
The specific heat of water is 
We need to find the final temperature of the water. The heat absorbed is given by the formula as follows :

So, the final temperature of the water is 28.98 degree Celsius.
