Answer : The water's temperature change will be,
Explanation : Given,
Density of water = 0.998 g/mL
Volume of water =
(conversion used : 1 L = 1000 mL)
Specific heat of water =
Heat absorbed =
(conversion used : 1 kJ = 1000 J)
First we have to determine the mass of water.
Now we have to calculate the change in temperature of water.
Formula used :
where,
Q = heat absorbed by water
m = mass of water
= specific heat of water
= change in temperature
Now put all the given value in the above formula, we get:
Therefore, the water's temperature change will be,
Answer: 292.81
Get Kelvin by adding 273 to the Celsius You set it up with 7.82/355K • 6.45/X
Cross multiply 7.82•X and 6.45•355
You get 7.82X=2289.75
Divide both sides by 7.82 to get x=292.81
Answer:
E. The atoms in amorphous silica do not pack as efficiently in three dimensions as compared to the atoms in quartz.
Explanation:
Quartz is a crystalline structure with a lattice which is very compact and produces flat faces that align with one another causing high density.
Silica has covalent bonding and forms a network structure. Silica, SiO2 is an amorphous solid and does not posses the same lattice or crystalline structure as Quartz, making it less dense.
It is known as the Magnetic Field.
