Answer:
The absolute pressure inside the ball is 1.25atm.
Explanation:
Given-
Volume, V = 5..27L
Temperature, T = 27°C
Gauge Pressure, Pg = 0.25 atm
Atmospheric pressure, Patm = 1 atm
Absolute pressure, Pabs = ?
We know,
Therefore, absolute pressure inside the ball is 1.25atm.

<span>Hydroelectric energy uses the movement of water to spin a turbine and produce electricity. Coal is a fossil fuel that is burned as an energy source, which results in emissions such as carbon dioxide, nitrogen, and sulfur. Coal use is associated with waste products both from the mining process to acquire the coal and also from the actual use of coal itself. Hydroelectric energy does not involve waste, but does pose potential problems to waterways. Coal use is more common than the use of hydroelectric energy.</span>
Main Answer:
Given data:
Mass of ice m = 12 grams = 12/1000 = 0.012 kg
Specific heat s = 4.18 KJ/ gm-1 C-1
Change in temperature t = t2 - t1
t = 100 - (-10)
t = 100 + 10 = 110C
Heat required Q = m x s x t
Q = 0.012 x 4.18 x 110
Q = 5.5176 KJ
Explanation:
What is heat?
Heat is defined as one of the forms of energy. It is a kinetic energy which can be transferred from one object to another object or medium. It cannot be destroyed or created. The units of heat is Joules in SI system and calories in CGS system.

Answer:
The correct statement is:
E - The entropy of the products is greater than the entropy of the reactants.
Explanation:
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O
As glucose is a large molecule and then it is transformed into many molecules of water and carbon dioxide, the entropy of the system increases. If the number of molecules increases, the disorder increases.
Initial state: 7 molecules (1 glucose + 6 oxygen)
Final state: 12 molecules (6 carbon dioxide + 6 water)
