Determine the amount of heat energy in joules required to raise the temperature of 7.40g of water from 29.0OC to 46.0 OC.
valina [46]

Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed = ?

m= mass of substance = 7.40 g

c = specific heat capacity = 4.184J/g^0C

Initial temperature of the water = T_i = 29.0°C

Final temperature of the water = T_f  = 46.0°C

Change in temperature ,\Delta T=T_f-T_i=(46.0-29.0)^0C=17.0^0C

Putting in the values, we get:

Q=7.40g\times 4.184J/g^0C\times 17.0^0C

Q=526J

The amount of heat energy in joules required to raise the temperature is 526 Joules

what volume of silver metal Will Weigh exactly 2500 .0 g the density of silver is 10.5 g/ cm3 squared
vovangra [49]

Hello!

The formula is density =  mass / volume

                    => volume = mass / density

volume = ?

mass = 2500.0 g

density = 10.5 g/cm3

volume = mass / density

volume = 2500.0 g / 10.5 g/cm3

volume = 2380.95 cm3

Hope this help!
