What variable represents thermal energy in the equation Q equals mcT?
In the equation ( Q = mc\Delta T ), the variable ( Q ) represents thermal energy. Here, ( m ) is the mass of the substance, ( c ) is the specific heat capacity, and ( \Delta T ) is the change in temperature. The equation calculates the amount of thermal energy absorbed or released by a substance when its temperature changes.

if q= mc delta T then we know that as the mass increases the heat transferred increases
What is the equation for specific equations?
Q = mc(delta)T Q = quantity of heat energy m = mass c = specific heat capacity different constant for each different substance (delta)T = difference in temperature (subtract high temp - low temp)
If 705g of water is heated 889J how much will its temperature increase?
To find the temperature increase, you can use the formula: ( Q = mc\Delta T ), where ( Q ) is the heat energy transferred, ( m ) is the mass of the substance, ( c ) is the specific heat capacity of the substance, and ( \Delta T ) is the change in temperature. Rearrange the formula to solve for ( \Delta T ) by dividing both sides by ( mc ): ( \Delta T = \frac{Q}{mc} ). Substitute ( Q = 889J ), ( m = 705g = 0.705kg ), ( c = 4.18 J/g°C ), and calculate to find the change in temperature.
How many degrees will J raise the temperature of g of water?
To determine how many degrees J will raise the temperature of g of water, we need to use the specific heat capacity formula: ( Q = mc\Delta T ), where ( Q ) is the heat added (in joules), ( m ) is the mass of the water (in grams), ( c ) is the specific heat capacity of water (approximately 4.18 J/g°C), and ( \Delta T ) is the change in temperature (in °C). Rearranging the formula gives ( \Delta T = \frac{Q}{mc} ). Without specific values for Q and g, we cannot calculate the exact change in temperature.
What variable represents specific heat in the equation Qmc delta t?
In the equation ( Q = mc\Delta T ), the variable that represents specific heat is ( c ). It denotes the amount of heat required to raise the temperature of one unit mass of a substance by one degree Celsius (or one Kelvin). The other variables in the equation are ( Q ) for heat energy, ( m ) for mass, and ( \Delta T ) for the change in temperature.
What is the formula to find specific heat of water Q?
The formula to find the specific heat of water ( Q ) is: ( Q = mc\Delta T ), where (m) is the mass of the water, (c) is the specific heat capacity of water, and ( \Delta T ) is the change in temperature of the water.
How many degrees will 340 J raise the temperature of 6.8g of water?
To find the temperature change, we need to use the formula: ( Q = mc\Delta T ), where ( Q ) is the heat, ( m ) is the mass, ( c ) is the specific heat capacity of water (4.18 J/g°C), and ( \Delta T ) is the temperature change. Substituting the values, we get: ( 340 = 6.8 \times 4.18 \times \Delta T ). Solving for ( \Delta T ), we find that the temperature will rise by approximately 12.75 degrees Celsius.
Q equals m plus x t plus c In this equation what does Q t and c represent?
In the equation Q equals m plus x t plus c, Q represents the total quantity or value being measured or calculated. t represents the variable or time period being observed or measured. c represents the constant term or the y-intercept, which is the value of Q when t equals zero.
If 57j of heat are added to an aluminum can with a mass of 17.1g what is the temperature change?
To find the temperature change, use the formula ( q = mc\Delta T ), where ( q ) is the heat added, ( m ) is the mass, ( c ) is the specific heat capacity, and ( \Delta T ) is the temperature change. The specific heat capacity of aluminum is approximately ( 0.897 , \text{J/g}^\circ\text{C} ). Rearranging the formula gives ( \Delta T = \frac{q}{mc} ). Plugging in the values: [ \Delta T = \frac{57 , \text{J}}{17.1 , \text{g} \times 0.897 , \text{J/g}^\circ\text{C}} \approx 3.66^\circ\text{C} ] Thus, the temperature change is approximately ( 3.66^\circ\text{C} ).
When does q equal delta h in a chemical reaction?
Q equals delta H in a chemical reaction when the reaction is at constant pressure and the temperature remains constant.
