Answer:
heat = 229139.43 cal
Explanation:
given data
specific heat of iron is 0.107 cal/g-°C C = 0.4494 J/g°C;
Mass of iron = 24.7 kg = 24700 g
temperature T1 = 880°C
temperature T2 = 13°C
solution
we know that Heat lost that is express as
heat loss = mcΔT .........................1
here m is the mass and c is specific heat capacity of iron and ΔT is the change in temperature
so here change in the temperature is = 880°C - 13°C
change in the temperature = 867°C
so put here value and we get
heat = 24700 × 0.107 cal/g-°C × 867°C
heat = 229139.43 cal

See explanation
Explanation:
The thermal energy of a substance is affected both by its mass and by its temperature. Thermal energy is defined as the total kinetic energy of all particles in an object.
Even though the cup of water has a higher temperature, the bathtub has more thermal energy because it contains much more mass of water compared to the cup. It will release more thermal energy to the surroundings compared to the cup of boiling water.
Answer:
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here metal X is having an oxidation state of +4 called as cation and is an anion with oxidation state of -3. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
is the formula of the resulting compound.
When the wind will be stronger, it will exert more force on particles and hence larger particles erodes
In short, Your Answer would be "True"
Hope this helps!
Renewable resources = Wind and water resources
Non - renewable = Fossil fuels , wildlife
