Verified step by step guidance

Identify the formula needed to calculate the heat required to change the temperature of a substance: \( q = m \cdot c \cdot \Delta T \), where \( q \) is the heat in joules, \( m \) is the mass in grams, \( c \) is the specific heat capacity in J/g°C, and \( \Delta T \) is the change in temperature in °C.

Determine the values given in the problem: mass \( m = 100.0 \) g, specific heat capacity \( c = 0.385 \) J/g°C, initial temperature \( T_{\text{initial}} = 18 \)°C, and final temperature \( T_{\text{final}} = 35 \)°C.

Calculate the change in temperature \( \Delta T \) using the formula \( \Delta T = T_{\text{final}} - T_{\text{initial}} \). Substitute the given temperatures to find \( \Delta T \).

Substitute the values for \( m \), \( c \), and \( \Delta T \) into the heat formula \( q = m \cdot c \cdot \Delta T \) to find the heat \( q \) in joules.

Perform the multiplication to solve for \( q \), ensuring that units are consistent and the calculation is done correctly to find the amount of heat required.
