Write in all formulas used to calculate heat.2. **Graph Explanation**: - The heating curve is a stepwise graph illustrating the phase changes and temperature increase of substance X. - The graph begins at 2°C and consists of several phases: - **Solid Phase**: Temperature increases until reaching the melting point of 14°C. - **Phase Change**: At 14°C, X transitions from solid to liquid, creating a plateau as it absorbs heat without a temperature change (fusion). - **Liquid Phase**: Temperature rises from 14°C to the boiling point of 86°C. - **Phase Change**: At 86°C, X transitions from liquid to vapor, forming another plateau as it absorbs heat (vaporization). - **Vapor Phase**: Temperature increases from 86°C to 120°C.b. **Task**: Determine the amount of heat necessary to change 30g of X from solid at 4°C to liquid at 14°C. - Use formulas for calculating heat in each phase and phase change: - Heating solid: \( q = m \times c \times \Delta T \) - Melting: \( q = m \times \text{Heat of Fusion} \)Where \( m \) is mass, \( c \) is specific heat capacity, and \( \Delta T \) is the change in temperature.
