Answers
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).
Answers
Answer:
300 J.
Explanation:
- The first law of thermodynamics is the law that demonstrates the conservation of energy.
- It states that the total energy of an isolated system can not be created or destroyed, but it may be transformed into another form.
- The energy released to the room is 300 J.
- So, according to the law of conversation of energy; the amount of heat removed from food inside of the refrigerator is 300 J.

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.

Final answer:
Phase changes occur at specific temperatures under standard pressure and involve either absorption or release of heat energy. This process involves the modification of kinetic energy and intermolecular forces.
Explanation:
The relationship between phase changes and temperature or heat energy is that phase changes occur at specific temperatures under standard pressure and involve either absorption or release of heat energy. This is based on the theory of kinetic energy and intermolecular forces. For instance, when ice melts to become liquid water (also known as melting), it does it at a specific temperature which is 0 degrees Celsius under 1 atm pressure. During this phase change, the ice absorbs heat energy from the surroundings without changing its temperature.
