Which form of energy is associated with the random motion of the particles in a sample of water?

chemical energy

electrical energy

nuclear energy

thermal energy

Explanation: Thermal energy is the energy that comes from the random motion of particles within a substance. In a sample of water, the particles (molecules) are constantly moving, and this movement is what we refer to as thermal energy. The faster the particles move, the higher the temperature and the more thermal energy the sample has.

Convert the boiling point of hydrogen chloride at standard pressure to kelvin.

Answer Explanation:
The boiling point of hydrogen chloride is given as -84.9°C. To convert Celsius to Kelvin, use the formula:
K = °C + 273.15
So, K = -84.9 + 273.15 = 188.25 K. Rounded to the nearest whole number, this is 188 K.

Solid X is placed in contact with solid Y. Heat will flow spontaneously from X to Y when

X is 20°C and Y is 20°C
Explanation: No heat will flow because both solids are at the same temperature; there is no temperature difference to drive heat transfer.

X is 10°C and Y is 5°C
Explanation: Heat always flows spontaneously from a region of higher temperature to a region of lower temperature. Since X (10°C) is warmer than Y (5°C), heat will flow from X to Y.

X is -25°C and Y is -10°C
Explanation: Even though the temperatures are negative, -10°C is warmer than -25°C. Heat would flow from Y to X, not from X to Y.

X is 25°C and Y is 30°C
Explanation: X is cooler than Y, so heat would flow from Y to X, not from X to Y.

The final temperature of the helium gas sample in degrees Celsius is _____.

Answer Explanation:
From the table, the final temperature is given as 300 K. To convert this to degrees Celsius, use the formula:

°C = K - 273

So, 300 K - 273 = 27°C.

Therefore, the final temperature of the helium gas sample in degrees Celsius is 27°C.
