The volume of liquid water is generally affected by temperature changes, but it also depends on other factors such as pressure and impurities. Assuming standard atmospheric pressure, pure water exhibits a unique property known as anomalous expansion, which means it contracts as it is heated from 0°C to 4°C and then expands as the temperature further increases.
At the starting point of 1 degree Celsius, the volume of water is typically close to its maximum density, which occurs at around 4 degrees Celsius. Therefore, at 1 degree Celsius, the volume of water would be very slightly larger than it would be at 4 degrees Celsius. However, the difference is negligible for practical purposes.
So, to answer your question, the volume of the water at a starting point of 1 degree Celsius is approximately the same as the volume at 4 degrees Celsius, assuming standard atmospheric pressure and pure water.
