Is cooking Ricea chemical change?

justify. Heat causes the breakdown of starches (long chain carbohydrates) into simpler to digest sugars (mono and dimer carbohydrates). This involves breaking chemical bonds, so it is a chemical change.

What is the chemical equation for cooking an egg?

CaCO3(s) + 2CH3COOH(l) Ca(CH3COO)2(s) + H2O(l) + CO2(g) Water and excess vinegar evaporate upon standing. Carbon dioxide (a gas) is released into the air during the reaction. After you dissolve the eggshell, the egg is surrounded by a membrane. (Actually, it’s two membranes, but they are held tightly together).

Is cooking rice exothermic or endothermic?

Cooking of rice is both irreversible and endothermic reaction. i.e once cooked rice cannot be made rice back and the rice absorbs heat from the external sources and utilizes for its cooking so it is endothermic.

Is formation of clouds a fast change?

The formation of clouds is a physical change because there is a phase transformation cycle of natural water from liquid to gas and then, gas to liquid. This process continuous occurring and very fastly. Hence, formation of clouds is a fast change.
