This in turn determines whether the substance exists in the solid, liquid, or gaseous state. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

Answer: Temperature of the substance determines the average kinetic energy of particles in a gas.

Explanation:

Average kinetic energy is defined as the average of all the kinetic energies of the particles in a system. It is a measure of temperature of the particles in a gas.

The equation used to calculate the average kinetic energy of the particles is given as:

$E=\frac{3RT}{2N_A}$

where,

R = Gas constant

T = Temperature of the gas

$N_A$ = Avogadro's number

E = Average kinetic energy of the particles

As, temperature is directly related to the average kinetic energy of the gas. Thus, the temperature of the particles increases, the average kinetic energy of the particles also increases and vice-versa.

Thus, temperature of the substance determines the average kinetic energy of particles in a gas.

Answer:

Nearly 80 per cent of organisations in North America and Europe were victims of cyber attacks last year and nearly half of cyber attacks used malware hidden in encrypted traffic to evade detection, a report said on Wednesday.

The encryption technology that is crucial to protecting sensitive data in transit such as web transactions, emails and mobile apps, can allow malware hiding inside that encrypted traffic to pass uninspected through an organisation’s security framework.

The report by US-based security company A10 Networks in partnership with Ponemon Institute surveyed 1,023 IT and IT security practitioners in North America and Europe, highlighting the challenges these professionals face in preventing and detecting cyber attacks.

Also, remember, light energy (from the sun) is a reactant for photosynthesis. The plant uses water sunlight and carbon dioxide to make sugars as well as oxygen. Plants, the organisms that carry out photosynthesis, are typically the first ate organism is a Food chain and so most other organisms energy came from the plant somehow. But the plant got its energy from the sun.
