The correct matches are as follows:
1. HYDRO POWER: Most common renewable energy source.
Hydro power refers to a type of energy which uses water to produce electricity. This type of energy is derived from the energy of falling water; the energy is used to drive the turbines that generate electricity. The quantity of electricity that can be generated in an hydro power plant depend on the quantity of water available and the height from which the water is falling. Hydro power is a renewable source of energy because of availability of water.
2. SOLAR: Depends on time of day and time of year.
Solar power is the type of electrical power that is derived from the energy of the sun. It is a renewable form of energy and it is considered to be the cleanest and most reliable source of energy. Solar panels are usually used to trap energy from the sun and to convert them to electrical energy. One property of solar power is that, the quantity of solar power that can be obtained depend on the strength of the sun light. On days and time of the year when there is little sunlight, little solar power can only be generated during this time.
3. COAL: Most polluting energy source.
Coal is obtained naturally from underneath the ground through mining. There are different types of coal and these coals were formed millions of years ago. Coal is a non-renewable energy source and is considered to be the most polluting energy source. Burning of coal releases greenhouse gases, which damage the ozone layers. The burning also resulted in production of gases such as carbon monoxide, which brings about acid rain. The extraction of coal also endangered the environment.
4. OIL: Liquid formed from remains of plants and animals.
Crude oil is a natural resource that is obtained from underneath the earth through the process of drilling. Crude oil was formed millions of years ago from the remains of plants and animals. Oil is one of the products that are obtained from the purification of crude oil. Oil is a fossil fuel and it is not renewable. Oil is majorly used to power vehicles and machines. Burning of oil [petrol], results in production of high amount of carbon dioxide and other gases, which pollute the environment.
5. BIOMASS: Renewable source formed from organic material.
Biomass are renewable and energy sources that are formed from organic materials. They are used to create electric power and other forms of power. Examples of materials from which biomass power are derived from are: animal wastes, forest debris, certain waste residues, certain crops and woody fuels. Energy in biomass are released in form of heat when they are burned. The heat is used to power turbines, which generate electricity.
Energy can neither be created nor be destroyed, which can only be transformed into one form or another. The energy obtained from different sources has different properties.
Thus, energy is a vital source required to carry out many actions and activities, which can be obtained from different sources.

Answer:
Given the word is '' HEURISTICS '' the Total no of letters is 10 Since C mus
Explanation:
Answer:
To solve this problem, we can use the calorimetry formula that relates the heat transfer between the system and the surroundings:
Q = mc∆T
where Q is the heat transfer, m is the mass, c is the specific heat capacity, and ∆T is the temperature change.
We can assume that the heat lost by the glass and the calorimeter is equal to the heat gained by the water. Therefore, we can write:
Qglass + Qcalorimeter = Qwater
Substituting the values given in the problem, we get:
mglass x 0.8372 x (26.6 - 90) + 7 x 1.23 x (26.6 - 24.3) = 75 x 4.184 x (26.6 - 24.3)
Solving for mglass, we get:
mglass = 10.8 g
Therefore, the mass of the glass was 10.8 g.
I hope this answer helps you understand how to use the calorimetry formula to find the mass of an object. Thank you for chatting with me.
