Help me find the qmetal and q water with the round and un rounded values

### Specific Heat Values - **The specific heat of water** is \(4.184 \, \text{J} \, \text{g}^{-1} \, \text{K}^{-1}\). - **The specific heat of zinc** is \(0.388 \, \text{J} \, \text{g}^{-1} \, \text{K}^{-1}\). ### Data Input Table #### Heat Calculations | Quantity | Unrounded | Rounded | |-------------|--------------------|--------------------| | \(Q_{\text{metal}} \, (\text{J})\) | [Editable Field] | [Locked Field] | | \(Q_{\text{water}} \, (\text{J})\) | [Editable Field] | [Locked Field] | The table provides fields for entering data for unrounded calculations of heat absorbed or released by metal and water. The rounded columns are locked, indicating that no data entry can be performed in these fields.

Expert Solution
Step 1

Specific Heat (c) : The amount of heat per unit mass of substance required to raise the temperature by one degree is known as specific heat. 

Relation between specific heat and  change in temperature  is given by the formula,

       Q = c•m•∆T

where, Q = Heat added, 

m = mass of substance,

∆T = change in temperature.
