How much heat in joules is needed to raise the temperature of 5 grams of iron?
Q = m x Cp x temp change then: Temp change = m x Cp / Q where: m = mass of matter Cp =specific heat of matter Q= heat
How do you find how much heat is gained in a specific heat problem?
To find the heat gained in a specific heat problem, you can use the formula: Q = mcΔT, where Q is the heat gained, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Simply plug in the values for mass, specific heat capacity, and temperature change to calculate the heat gained.
How much heat must be transferred to liquid water to change the water's temperature from 27 C to 32 C?
This heat is: 5 x 4,18 x m = 20,9 x m (in calories) where m is the mass of water.
Equation to calculate heat gained or lost by an object?
c = Q / (m(change in temperature)) Where, c = specific heat capacity Q = amount of heat needed m = mass Change in temperature = initial temperature - temperature(after) Take note that this equation cannot be used in calculating the change in state - melting and boiling Because temperature do not change. We therefore use: Q = lv x m Where, lv = latent heat of vapourisation (for boiling/condensation ONLY) m = mass Q = lf x m Where, lf = latent heat of fusion (for melting/freezing ONLY)
What M describes rocks that were formed when existing rocks were heated or squashed?
Metamorphic rocks are formed when existing rocks are subjected to high heat and pressure, causing them to recrystallize into new forms without melting. This process typically occurs deep within the Earth's crust or mantle.

How much more heat needs to be added to water at 100 degrees centigrade in order to change it to steam?
Heat required to have such a change of state is called latent heat. If L J/kg is the latent heat per kg of water then for M kg of water we need M* L joule of heat energy
Choose the correct formula for determining specific heat.?
(change of heat) ____________________ (change of temp)(mass)
What is the relationship of mass of an object to the amount of heat required to change its temperature?
The bigger he mass the more heatt required to change its temp.erature; Heat=m(T2-T1)
What m described rocks that were formed when existing rocks were heated or squashed?
Metamorphic rock. This can naturally form an existing Sedimentary, Igneous or Metamorphic rock due to exposure to heat and/or pressure.

What is the formula for calculating the change in temperature (T) using the specific heat capacity (c) and the mass (m) of a substance, expressed as mcT?
The formula for calculating the change in temperature (T) using the specific heat capacity (c) and the mass (m) of a substance is mcT.
Equation to calculate heat gained or lost by an object?
c = Q / (m(change in temperature)) Where, c = specific heat capacity Q = amount of heat needed m = mass Change in temperature = initial temperature - temperature(after) Take note that this equation cannot be used in calculating the change in state - melting and boiling Because temperature do not change.

How many joules of heat are needed to change the temp of 40 g of water?
To calculate the heat needed to change the temperature of water, you can use the specific heat capacity of water, which is 4.18 J/g°C. If you're specifying the temperature change, you would use the formula Q = m * c * ΔT, where Q is the heat energy, m is the mass of the water (40 g), c is the specific heat capacity of water, and ΔT is the temperature change.
What is the correction equation Q m x c x T rearranged to solve for specific heat?
The specific heat (c) can be calculated by rearranging the equation as c = Q / (m x T), where Q is the heat energy transferred, m is the mass of the substance, and T is the temperature change.
