- Question 2A Celsius thermometer reads an outdoor temperature of 16.33 Celsius what is the temperature in Fahrenheit (do not use units in final answer)20°C 25°C During day time, water is colder than the sand. Which has higher specific heat capacity, water or sand? * O Incomplete information is given. O Sand, as increases its temperature increases easily. Sand, as it needs less energy to increase its temperature O Water, as it needs more energy to increase its temperature.
- A water heater with a maximum power output of 650W is used to increase the temperature of water for 15 minutes. What is the temperature increase in Celsius if the water has a mass of 5kg? Round-off your answer to the nearest whole number. Do not type the unit of your final answer. *9,3 skill application The heating curve below shows the change in temperature of a 20 g sample of a substance as energy is added to the substance as heat.
