Suppose a 14 gram sample of iron is heated from 20C to 25C The specific heat of iron is 0.11C How much heat energy was absorbed by the iron?

it depends on the units of the specific heat, but if they are J / goC then you would take your delta T (25-20) and multiply it by your mass (14g) and multiply by your specific heat.
In this case it would be 5 * 14 * .11 = 7.7 (with whatever units of energy your specific heat is in.) Just make sure your units cancel out and you will get it right!

The specific heat of gold is 0.031 caloriesgram and degC. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 and degC how many calories of heat energy were absorbed by?
The needed heat is:Q = 10 x 20 x 0,031 = 6,2 calories
Do atoms get hotter when matter is heated?
When a matter is heated then the vibration of atoms increase and hence the kinetic energy increases.
What does most matter do when heated?
Most matter EXPANDS when heatedmost matter expands when heated
In which country were 89 of all homes heated by geothermal energy in 2006?
Iceland
Why hot sand heats the air not an example of conduction?
I think it is an example on convection.
When a gas is heated is all of the absorbed energy converted to kinetic energy or potential?
When a gas is heated the energy is converted to kinetic energy.
Does matter gain energy and evaporates when it is heated?
Matter gains energy when it is heated due to a thermal transfer. It does not always evaporate when heated as this varies based on the specific material being heated.
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
When a gas is heated does all of the absorbed energy convert to kinetic energy If not please tell what it is converted to part kinetic and part potential energy or just potential energy?
The gas will have thermal energy given by its specific heat capacity (at constant pressure or volume depending on the situation) times the rise in temperature. This thermal energy is possessed because of the increased kinetic energy of its molecules, due to the rise in temperature.
How much energy would be absorbed as heat by 75g of iron when heat from 295k to 301k?
o calculate the amount of energy absorbed by 75 grams of iron when it is heated from 295K to 301K, we need to use the specific heat capacity of iron. The specific heat capacity of iron is 0.45 J/g*K. We can use the equation: Q = m * c * delta T Where Q is the energy absorbed, m is the mass of the substance (in this case, 75g of iron), c is the specific heat capacity of the substance (0.45 J/g*K for iron), and delta T is the change in temperature (301K - 295K = 6K). Plugging in the values, we get: Q = 75g * 0.45 J/g*K * 6K = 21 J 𝓦𝓮𝓲𝓻𝓭 𝓣𝓮𝔁𝓽𝓱𝓽𝓽𝓹𝓼://𝔀𝔀𝔀.𝓭𝓲𝓰𝓲𝓼𝓽𝓸𝓻𝓮24.𝓬𝓸𝓶/𝓻𝓮𝓭𝓲𝓻/449013/𝓕𝓻𝓪𝓷𝓴𝓫𝓪𝓱𝓪𝓵𝓵𝓪/ So the 75 grams of iron will absorb 21 joules of energy as heat when it is heated from 295K to 301K.

The needed heat is:Q = 10 x 20 x 0,031 = 6,2 calories
The color of light given off when a sample is heated corresponds to?
heated of the element heat absorbed by the sample amount of energy added to the sample energy difference between the ground state and exited states of an element.
The atmosphere is heated chiefly by radiation emitted by Earth?
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
When oil is heated then temperature would be?
Higher, I suppose.
Why do electrons jump when heated?
electrons jump energy levels becouse each level has a specific amount of energy needed inorder to be in that level. when an electron gets enough energy it jumps to the next level it can possible be in with that amount of energy.
The energy needed to melt or boil 1kg of a substance by 1C?
The value depends on the material being heated. This value is called the specific heat capacity, or just specific heat for short.
