Answer: the correct answer is option(d).
Explanation:
Energy required ,Q= ?
Mass of water , m = 17 grams
Temperature difference or = 15 °C
Specific heat value of water = 4.186 J/g °C
From the given value the , nearest value to to our calculated answer is 1067 J that option (b).
Hence, the correct answer is option (d).

Explanation:
In gases, the molecules are held together by weak Vander waal forces. Due to this they have more kinetic energy and hence, more number of collisions take place between the molecules of a gas.
Therefore, they tend to diffuse at a faster rate and distance traveled by them is more as compared to the distance traveled by the molecules of a liquid.
On the other hand in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases but not strong enough as they are in solids. Due to this molecules of a liquid are able to slide past each other. Hence, they have medium kinetic energy.
Therefore, less number of collisions take place between molecules of a liquid as compared to gases.
Thus, we can conclude that particles collide in gas so, substance X is a gas.

The correct answer is option D, that is, protons and neutrons.
The center of an atom is known as the nucleus, it comprises nucleons, that is, neutrons and protons, and is enveloped by the cloud of electrons. The nucleus exhibits the majority of the mass of the atom in spite of being a very small constituent of the atom. Approximately all the atom's mass is formed of the neutrons and protons in the nucleus with a very small donation from the orbiting electrons.

Technology is built to give means, tools, and machinery for the preservation of the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials, which is how technology and the environment are interdependent.
What is global warming ?
The gradual increase in the planet's surface temperature is known as global warming. Although this warming trend has been around for a while, the burning of fossil fuels has greatly accelerated its pace over the past century. The amount of fossil fuels burned has increased along with the size of the human population.
The two main ways that these technologies have harmed our planet are through pollution and the depletion of natural resources. When dangerous or excessive levels of gases like carbon dioxide, carbon monoxide, sulfur dioxide, nitric oxide, and methane are released into the earth's atmosphere, air pollution results.
Technology and society have a reciprocal interaction. Technological advancement shapes society, while technological advancement drives it.
Thus, the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials.
