Consider the temperature versus time graph below. A graph of temperature versus time has time on the horizontal axis and tempera
ture in degrees Celsius from negative 20 to 140 on the vertical axis. A line extends through the following points: 0, negative 10; 4, 0; 7, 140; 18, 120; 19, 125. At what temperature is the substance a heated gas? at 100°C below 0°C above 100°C between 0°C and 100°C
