According to law of conservation of energy, the given example shows that energy is transferred to friction and vibration as it is converted between different forms as it can neither be created nor destroyed.
According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a process .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

Answer:d
Explanation:
Answer:
A large quantity
Explanation:
A large quantity will take much longer to melt compared to a small quantity of the same matter.
The rate of melt of a substance is particularly a function of the nature of the substance and the amount of energy supplied to it.
If we assume that we are dealing with different quantities of the same substance, then the one that has more mass will melt faster because less energy would be required to change its state.
A large quantity of matter will take more time to melt.
Answer:
1419.21 mL
Explanation:
From the question;
We are required to determine the volume of the oil in mL
Volume = Mass ÷ Density
= 1.3 kg ÷ 0.916 kg/L
= 1.41921 L
BuT, 1 l = 1000 mL
Therefore;
Volume = 1.41921 L × 1000 mL/L
= 1419.21 mL
Hence, the volume of olive oil is 1419.21 L
To find the volume of the oil, we can use the formula density = mass/volume. The density of olive oil is approximately 0.92 g/mL. Converting the mass of the oil from kilograms to grams, we find that the volume of the oil is approximately 1413.04 mL.
To find the volume of the oil, we need to convert the mass of the oil to volume using its density. The density of olive oil is approximately 0.92 g/mL. First, we need to convert the mass of the oil to grams:
1.3 kg * 1000 g/kg = 1300 g
Next, we can use the formula density = mass/volume to find the volume:
0.92 g/mL = 1300 g/volume
Solving for volume gives us:
volume = 1300 g / 0.92 g/mL = 1413.04 mL
Therefore, the volume of the oil is approximately 1413.04 mL.

Answer:
Chemical Formula: AlCl₃
Chemical Name: Aluminium Chloride
Properties are given below.
Explanation:
Chemical Formula:
Chemical formula depicts the total number of elemants forming a particular compound. It is common that all compounds are neutral in nature despite of the internal charges they contain. As given Aluminium has a + 3 charge while Chlorine has a -1 charge, therefore, to make a neutral compound we will require 3 Cl⁻ ions to neutralize one Al³⁺ ion hence, the chemical formula will be AlCl₃.
Chemical Name:
According to rules ionic compounds are named by naming the positive part first followed by negative part. In this case Al³⁺ being is name d first followed by Cl⁻ (remember the -ine in anions is replaced by -ide) hence, this compound will be name as Aluminium Chloride.
Properties:
Few physical and chemical properties of AlCl₃ are;
(i) It melts at 192.4 °C
(ii) Highly Soluble in water
(iii) It has a density of 2.48 g/cm³
(iv) Poor conductor of electricity
(v) It is used as catalyst in many organic reactions
(vi) Reacts with silver nitrate to form silver chloride and Aluminium Nitrate
