Answer:
 If the Kelvin temperature of a gas is increased, the volume of the gas increases. This can be understood by imagining the particles of gas in the container moving with a greater energy when the temperature is increased.
Explanation:
If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure. Conversely if you cool the molecules down they will slow and the pressure will be decreased.
To calculate a change in pressure or temperature using Gay Lussac's Law.
 
        
             
        
        
        
Since energy can neither be created nor destroyed and it just changes from one form to another...so...
A.
Energy is neither lost nor gained as electrical energy is transformed into the energy of sound.

Answer:
2.2nC
Explanation:
Call the amount by which the spring’s unstretched length L, 
the amount it stretches while hanging x1 
and the amount it stretches while on the table x2. 
Combining Hooke’s law with Newton’s second law, given that the stretched spring is not accelerating, 
we have mg−kx1 =0, or k = mg /x1 , where k is the spring constant. On the other hand, 
applying Coulomb’s law to the second part tells us ke q2/ (L+x2)2 − kx2 = 0 or q2 = kx2(L+x2)2/ke, 
where ke is the Coulomb constant. Combining these, 
we get q = √(mgx2(L+x2)²/x1ke =2.2nC
 
        
             
        
        
        
The mass of this bag of cement in S.I. units (kg) is equal to 0.062 kilograms.
<u>Given the following data:</u>
- Mass of cement = 62 grams.
To calculate the mass of this bag of cement in S.I. units (kg):
<h3>How to convert to 
S.I. units.</h3>
In Science, kilograms (kg) is the standard unit of measurement or S.I. units of the mass of a physical object. Thus, we would convert the value of the mass of this bag of cement in grams to kilograms (kg) as follows:
<u>Conversion:</u>
1000 grams = 1 kilograms.
62 grams = X kilograms.
Cross-multiplying, we have:
X = 
X = 0.062 kilograms.
