Answer 1

Answer:

marks as brilliant please I hope my answer will help you I need only 9 brilliant answer

Explanation:

An indifference curve is a locus of all combinations of two goods which yield the same level of satisfaction (utility) to the consumers. Since any combination of the two goods on an indifference curve gives equal level of satisfaction, the consumer is indifferent to any combination he consumes

Answer 2

QuestioN :-

Define Heat Energy

AnsWeR :-

Heat energy is all around us such as in icebergs, volcanoes, and our bodies. Every matter has heat energy.

The result of the movement of minute particles known as atoms, molecules, or ions in liquids, solids, and gases is nothing but heat energy. Heat energy can be transferred by one substance to another and the flow because of the temperature difference between two objects is known as heat.

Diff. Ways to transfer heat energy :-

Convection :-

transfers heat energy via air and liquids. The particles move apart and become less dense as the air heats up and hence causes air to rise. While cooler air moves in from below and heats up.

Radiation :-

warms the air using heat waves that radiate out of the hot object in all directions until absorbed by other objects. Heat transfer by radiation takes place at the speed of light and travels great distances.

Conduction :-

transfers heat through one object to another when in direct contact. The traveling molecules of a warm object can increase the energy of the molecules in a cooler object. Solids conduct heat better than gases and liquids since particles are close together.

Examples of heat energy :-

The biggest example of heat energy in our solar system is the sun itself. The sun radiates heat to warm us up on the planet earth. When the burner of a stovetop is very hot, it is a source of heat energy.
