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

There is not enough information in this problem to answer the question. You must know the mass of the iron to find the amount of joules used to heat the iron.
decrease,because the cube of sugar absorb some heat
Melting point is the temperature at which something melts. Like ice has a melting point of 0 Celsius. The heat of fusion is the heat energy that is absorbed (or released) when a substance melts (or freezes) an is measured in energy units, either calories or joules. Ex. One gram of ice must absorb 80 calories of heat energy to change into liquid water.
The enthalpy of fusion, or Specific heat of fusion/melting is the temperature that it takes for a substance to freeze/melt. Generally it is much greater than it would ordinarily take for the substance to increase 1 degree Celsius in either solid or liquid phase. So, while at the freezing/melting point, the substance can absorb energy without changing the temperature during the state change.
The temperature decrease because evaporation is an endothermic process, absorb heat.
As temperature increases, the ability for water to absorb CO2 decreases. That is why we see higher CO2 when temperature rises in our atmosphere.
The temperature of Mars is between -50 and 25 degrees Celsius. The temperature for Venus is among 300, 500 and 600 degrees Celsius. Venus never attained a temperature of 0 degrees Celsius though Mercury attains it because of the thicker surface to absorb more heat from the sun when serious burns result from 100c water or steam something.
Water must to absorb 4,184 Joules of heat for the temperature of one gram of water to increase 1 degree Celsius (°C).

1) oceans absorb carbon-dioxide from the atmosphere, thereby bringing down the temperature 2) oceans emit heat from the sunlight they absorb and increase the temperature of the surrounding atmosphere.
There are 1000 g in one liter Use the formula Q=mc(delta)T Q=1200g(1calorie/g degrees celsius)(70 degrees - 20 degrees) Q=60,000 calories Q=60 kilocalories

If the surrounding air is zero degrees Celsius, steel and wood must have also the temperature of zero degrees Celsius. Wood is not warmer as many people believe. Although the temperatures are equal, you will perceive the steel as colder to touch. This is because it will absorb heat from your fingers more quickly than the wood (as it attempts to reduce your finger temperature to zero).

Both ice and liquid water can exist at 0 degrees C. However, ice has a very significant heat of fusion (the number of calories required to melt melt each gram), whereas water has only its 1 calorie per gram per degree C specific heat. Therefore, ice (which must melt before it can go above 0 degrees) must absorb much more heat to increase its temperature than water at 0 degrees. In consequence, ice is far more effective as a cooling agent.
