Answer:
603000 J
Explanation:
The following data were obtained from the question:
Energy required (Q) =...?
Mass (M) = 10000 g
Specific heat capacity (C) = 2.01 J/g°C
Overheating temperature (T2) = 121°C
Working temperature (T1) = 91°C
Change in temperature (ΔT) =.?
Change in temperature (ΔT) =T2 – T1
Change in temperature (ΔT) = 121 – 91
Change in temperature (ΔT) = 30°C
Finally, we shall determine the energe required to overheat the car as follow:
Q = MCΔT
Q = 10000 × 2.01 × 30
Q = 603000 J
Therefore, 603000 J of energy is required to overheat the car.
A) that something new had formed.
Properties of the following are:
Alpha particle - positively charged particle (+) that consists of two electrons and two neutrons.
Cathode rays - it is the stream of electrons (negatively charged) found in vacuum.
Protons - are particles that carry positive charge and is present inside the nucleus of an atom.
Electrons - are particles that carry negative charge and is present in the orbits of the atom.
Neutrons - electrically neutral particle (0 charge) present inside the nucleus of an atom. However, it has its own mass.
Answer:
A molecule is a bunch of atoms combined.
An atom is the smallest part of an element, that you can get without splitting the nucleus of the atom.
Molecules are made of more two or more atoms joined together. The atoms can be same or different elements. A single molecule is the smallest piece of matter you can have without changing its properties.
