Answer: The correct answer is option d.
Explanation: Energy stored into gasoline is converted into another form of energy. This was very well explained on the basis of Law of conservation of energy. This law states that energy is conserved in the system which means that energy is converted from one form to another form.
The energy stored into gasoline is converted into mechanical energy which helps the car to move and some of the energy is lost in the form of heat.
Hence, the correct answer is Option d.
The answer would be the ability to be tested. If a hypothesis is testable, it would of course lead you to test it. Which, by definition is a new experiment.
Answer:
The molar mass of unknown gas is 145.82 g/mol.
Explanation:
Volume of oxygen gas effused under time t = 8.24 mL
Effusion rate of oxygen gas = 
Molar mass of oxygen gas = 32 g/mol
Volume of unknown gas effused under time t = 3.86 mL
Effusion rate of unknown gas = 
Molar mass of unknown gas = M
Graham's Law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
The variable X is the effective nuclear charge, and it remains constant down a group.
Discussion:
The effective nuclear charge is referred to as the actual amount of positive (nuclear) charge experienced by an electron in a polyelectronic atom.
The effective nuclear charge experienced by an electron is otherwise called the core charge.
It is mathematically evaluated as the difference in the atomic number and the core electrons. and since elements in the same group have equal number of Valence electrons, the effective nuclear charge is constant down the group.
