how much energy would be needed to warm 7.40 g of water by 55 degrees celcius
q = mass x specific heat x delta T.
Note the correct spelling of celsius.

To calculate the amount of energy needed to warm water, you can use the specific heat capacity of water. The formula for calculating the energy is:
Energy = mass × specific heat capacity × temperature change
1. Determine the mass of water:
Given: mass = 7.40 g
2. Determine the specific heat capacity of water:
The specific heat capacity of water is approximately 4.18 J/g°C.
3. Determine the temperature change:
Given: temperature change = 55°C
Now, we can use the formula to find the energy:
Energy = 7.40 g × 4.18 J/g°C × 55°C
After performing the calculation, the energy required to warm 7.40 g of water by 55 degrees Celsius will be given in joules (J).
