Explanation

• Solar panels convert sunlight into electrical energy using special cells.
• Solar energy is a renewable and clean source of energy.
• These cells are called photovoltaic (PV) cells because they generate electricity when exposed to light.
• The technology is based on the photovoltaic effect, discovered in 1839.

Explanation

• Bacteria are prokaryotic organisms, meaning they do not have a true nucleus.
• Their genetic material (DNA) is not enclosed in a membrane-bound nucleus.
• Instead, the DNA is present in a region called the nucleoid within the cytoplasm.
• Therefore, bacterial DNA is found floating in the cytoplasm of the cell.

Additional information:

• In contrast, eukaryotic cells (plants, animals, fungi) have DNA enclosed inside a nucleus.

Explanation

• A chemical reaction that releases heat energy to the surroundings is called an Exothermic Reaction.
• In such reactions, energy is produced in the form of heat, light, or flames.
• Examples include combustion of fuel, respiration, and neutralization reactions.

Additional information:

• An endothermic reaction, which absorbs heat from the surroundings.

Explanation

• The branch of chemistry that studies heat energy released or absorbed during chemical reactions is called Thermochemistry.
• It explains how heat changes occur during reactions such as combustion, neutralization, and dissolution.
• It deals with concepts like enthalpy change (ΔH), exothermic reactions, and endothermic reactions.

Explanation

• The formation of hydrogen and oxygen from water, which is an example of a decomposition reaction: 2H2O → 2H2 + O2
• In this reaction, water (H2O) decomposes into hydrogen (H2) and oxygen (O2).
