Is the average kinetic energy of particle in a block of ice at 0 degrees the same as or different from the average kinetic energy of the particle in a gas-filles container at 0 degrees Celsius?
the same
A 38 kg block of lead is heated from 26 degrees Celsius to 180 degrees Celsius how much heat energy does the block of lead absorb to increase its temperature this much?
The specific heat of lead is 0.0305 K cal/kg deg C. The heat absorbed will be 38x(180-26)x0.0305 = 178.5 Kcal = 746.1 K joules
Does a block of ice contain heat energy?
It depends upon the condition of the ice and the environment it is in. For example, a block of ice in room temperature does not give off energy - to the contrary, it absorbs energy as it melts. . But a block of ice at -5oC that is set in freezer that is -20oC will give off its thermal energy until the block of ice's temperature falls to the freezer's temperature.
How cold for how long will it take for just water to freeze in a car?
Ok, this is based on equations 0 degrees Celsius is freezing and water will freeze at zero Celsius, but the time to freeze in direct relationship to volume so depending on your vehicle it would take anywhere to 4-6 hours at zero degrees Celsius. For every degree below 5:1 ratio -1 degrees Celsius the 2.5-4.75 hours to freeze. At -20 1 hour or less, to crack the block 2-3 hours. -40 degrees Celsius would take 22 min to freeze and to crack the block 1:10.
What units does a thermometer measure?
A thermometer measures thermal energy (heat energy) by measuring temperature in celsius, kelvin, or Fahrenheit degrees. Note that temperature can be used as an indicator of thermal energy, but it is not a direct measure of it. A masonry brick at a given temperature has more thermal energy than a block of pine (wood) the same size at the same temperature.

Which statements are true about a block of ice at -10 degrees Celsius as you continue to apply heat?
Thre temperature of the block of ice increases until you reach 0 degrees C when the block of ice begins to melt.

Temperature of the moon?
The temperature on the moon varies from -233 Celsius (-387 Fahrenheit) at night to 123 Celsius (253 Fahrenheit) during the day. Because the moon has no atmosphere to block some of the sun's rays or to help trap heat, its temperature varies greatly between day and night.
If the temperature outside is 3 degrees celsius and there is a steel block what will the block's temperature be after one hour if there is a wind chill factor of -20 degrees celsius?

What is the final temperature if 200 Joule of heat is removed from 50N block of ice initially at 25 degrees Celsius?
If you can find a block of ice at 25ºC ... or even a picture or a folk legend of one ... I'll go look up the conversion of joules to calories and work this out for you.
