Answer: 4.56 Joules
Explanation:-
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = ?
m= mass of substance = 2.5 g
c = specific heat capacity = 
Initial temperature = 
= 25.0°C
Final temperature = 
= 29.9°C
Change in temperature ,
Putting in the values, we get:
The heat absorbed by gallium must be 4.56 Joules
Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:
P = k / V
k is equal nRT
P1V1 = P2V2
P2 = 101.325 ( 4.65 ) / .480 = 981.586 kPa
Answer:
b
Explanation:
electrons lie in the orbits of the atom. they are negatively charged and they are very small in size. they have very less mass than proton. ele tron has 1/1840 mass of proton.
Answer:
to understand the human life
Explanation:
hope this helps :)
Answer:it would have a negative charge because electrons are negative
