In general, the average kinetic energy increases at higher temperatures for gases. Since gases are quite compressible, the effects of higher or lower temperature are significant.

Cold is stronger and cancels the heat. The particles in the cold water had less kinetic energy.] Compare the kinetic energy of the hot-water particles and the particles in the final mixture. [The particles in the hot water had more kinetic energy, or were moving faster, than the particles in the mixture.]

Heating water causes the water molecules to gain kinetic energy and speed up. It takes more energy to raise the temperature of a large amount of water because more molecules need to have their speed changed.

liquid

Solid particles

This means that when the temperature of an object is higher, then its molecules have greater average kinetic energy than an object with lower temperature. This means that a molecule in a gram of steam has more kinetic energy than a molecule in a gram of ice. This is because steam has a higher temperature than ice.

Water, like many substances, contains two kinds of energy. The first kind of energy is called kinetic energy. Because of kinetic energy water can flow and waves can exist. But water can also contain potential energy.

When liquid water is cooled below -42 degrees F, it crystallizes into ice too quickly for scientists to measure the temperature of the liquid.

solid state

Solids have the lowest kinetic energy whereas gases have the highest kinetic energy. Hence, hydrogen has the highest kinetic energy among the above examples.

Potential energy for water at 0 degrees is greater than potential energy for ice at 0 degrees. You have to put in energy to convert ice to water at 0 degrees. Since energy is conserved, water must have higher energy than ice.

Rajasthan clinched the top position in the list of states with the highest estimated solar energy potential in the country. It is having an aggregate solar power potential of 142.31 gigawatts (GWp).

The southern state of Tamil Nadu tops the list with ~9.3 GW of cumulative wind installations, representing a 25% share of the total installed capacity in India as of Q1 2020. Since 2016 to 2019, Tamil Nadu has been the leading wind installer in the country.

Tamil Nadu The south Indian state of Tamil Nadu tops the list, with an annual wind power output of around 9,000 MW per annum — recording 8,631 megawatts (MW) at the end of 2018 and 9,075MW in 2019.

1. Karnataka — 7,100MW. The south-western state of Karnataka heads India’s list of states producing solar energy. With a total installed solar power capacity of about 7,100MW – notwithstanding the 1,000MW of projects in the pipeline – Karnataka is way ahead of the other states.

According to the government documents reviewed by Mint, the Uttar Pradesh government had identified Prayagraj that hosts the Kumbh Mela, the largest global human congregation, to be one of these marquee solar cities; as part of ministry of new and renewable energy’ (MNRE) ‘Development of Solar City Programme’.

China

The Kutch solar project will replace the 2,000 MW solar park in Pavagada, Karnataka, as the “world’s largest”. The Pavagada plant, which opened in 2018, supplies over 19 per cent of the country’s solar power, and had an installed capacity of 27,199 MW at the end of 2018.
