how much heat will be carried by 4 gm aluminium at 40 C temperature?

To calculate the amount of heat carried by a substance, you can use the equation:

q = m * c * ΔT

where:
q is the amount of heat (in Joules),
m is the mass of the substance (in grams),
c is the specific heat capacity of the substance (in J/g°C),
ΔT is the change in temperature (in °C).

For aluminum, the specific heat capacity is 0.897 J/g°C.

Given:
m = 4 g
ΔT = 40°C

Substituting the values into the equation, we can calculate the amount of heat carried by the aluminum:

q = 4 g * 0.897 J/g°C * 40°C
q = 143.52 J

Therefore, 4 grams of aluminum at a temperature of 40°C will carry 143.52 Joules of heat.

To calculate the amount of heat carried by a substance, you need to use the formula:

Q = mcΔT

Where:
Q = Heat carried (in Joules)
m = Mass of the substance (in grams)
c = Specific heat capacity of the substance (in J/g°C)
ΔT = Change in temperature (in °C)

In this case, the mass of the aluminum is 4 grams, the specific heat capacity of aluminum is 0.897 J/g°C, and the change in temperature is 40°C.

Substituting these values into the formula:

Q = (4 g) * (0.897 J/g°C) * (40°C)

Q = 143.52 Joules

So, 4 grams of aluminum at a temperature of 40°C will carry approximately 143.52 Joules of heat.
