A gas thermometer is used as a standard thermometer for measurement of temperature. When the gas container of the thermometer is immersed in water at its triple point 273.16K, the pressure in the gas thermometer reads 3.0 x 10^4 N/m^2. When the gas container of the same thermometer is immersed in another system, the gas pressure reads 3.5 x 10^4 N/m^2. The temperature of this system is therefore
