By using laser-induced thermal acoustics, we demonstrate a non-invasive and remote method to measure the speed of sound and temperature ranging from 278 K to 341 K in distilled water at atmospheric pressure. The accuracies of the measured speed of sound and temperature were found to be 3% and 4%, respectively. Single-shot precisions based on three standard deviations of 20 samples were within 4% for the speed of sound and the temperature. The time resolution for each measurement was 300 ns.
